I rented this dress as a larger size backup but as soon as I tried it on, I knew it was the dress I would be wearing for my event! I usually wear a size 8 but the 10 fit perfectly. I have a larger bust (36DD) so the bigger size was perfect for me, If you are less busty, I would imagine your usual size would fit perfectly. The fabric is very lux with a really stunning shine and the color is to die for! This is a dress I really wish I could have kept!

OH. MY. This dress is amazing. I wore this to my medical residency graduation, so needed to be appropriate and professional with faculty and colleagues. It was the perfect combo of edgy and conservative. The cut of the dress is insanely flattering with nice thick fabric that hides bumps.  I was scared because there were no reviews yet but this dress was worth it!! I am 5'6" and the length hit just below the knee.  It had a nice structured bodice so I went braless. The one shoulder drapes really nicely but does add a bit of dimension to your frame. There are small black stripes down either side of the dress that didn't really show up in pictures, but it pushed me to use silver shoes/jewelry/clutch rather than gold. The ONE thing to keep in mind- if you chose a size that is tight on the hips, there is no slit at the bottom, so I was-- 1) taking small steps and 2) really struggling to pull the dress up to pee!!! I thought I was going to get stuck in the bathroom stall with this dress around my waist....

Overall though, I have nothing but high praise for this stunning dress. I got so many compliments, including from our department chair who yelled "you look GORGEOUS!" when I walked in. Not bad.

I wore to my graduation celebration. There isn't too much give in the fabric and it's a straight skirt, so was a little tight across my hips. Nothing to keep me from having a great time. I usually wear a 2/4, I tried on the 2,4, and 6 and the 4 fit the best. The 6 didn't give me too much more room in the hips and was too big across the top. It was such a fun dress, so many compliments! 


I rented this for an evening awards dinner that turned out to be a surprise wedding! I agree with other reviewers that the dress runs small, so definitely rent your actual size and one size up because there's not much give or stretch to the fabric, which has more of a quilted/woven feel. The color is a vibrant blue, and the shoulder strap in the front and back drapes across giving the dress giving it more of an elegant look and regal feel. Pair this dress with some gold, silver or even green shoes and accessories and you're good to go!  One thing though is the zipper is VERY stiff! You'll need someone to zip and unzip you for this dress.

I tend to run between a 14 and a 16, in this case I opted for the 16 as it was more comfortable, but it was big through the bust and waist. This dress is GORGEOUS. I received compliments all night long and I felt beautiful. I totally regret not getting a better picture of me in this dress!

The blue looks amazing in pictures, especially if you are in an outdoor setting.  I have a pear-shaped body so although if was a little tight for the lower part of my body, it was enough to where I could still dance majority of the night (just don't try to do the stanky leg and you'll be alright). This dress also works really well if you aren't very busty. The top did great in creating an illusion there. I received compliments all night, I am so glad I decided to go with this dress! 

This was an amazing dress. How amazing, you ask? So amazing that when I found it on sale online a few months later, I bought it! Everything about this dress screams classic, sophisticated elegance, but with a hint of va-va-voom. The fabric, the color, the cut, everything is perfection. I will caution that this dress does run a bit small - it's made to be very snug. I had to unzip it to use the restroom, as there is no slit at the bottom and therefore no way to get the skirt hiked up! This may not be the best dress for ladies with large chests, as I am a 32A. 

Pros: beautiful color, style is classic and elegant, adore the black detailing on the sides

Cons: fit in the waist is a little snug for my comfort

Overall loved this dress!

I honestly wish I took more photos than this one but I was so consumed with coordinating the event. The material is super nice and breathable so with all the running around I had to do, I still looked very well put together  especially with the bold, royalty looking blue. Oh and the fit was perfect for me!!

Fit well - was able to wear a strapless bra. It was a great color, even though the dress did show some wear. I have full hips for my size and it was a bit tight, but the 2 was too large. Would recommend for someone with a smaller chest, like me! 

I got so many compliments on this dress! While it looks silky in the picture it is a thicker fabric that helps to hide any problem areas. I am 5'1" and it was just longer than knee length. 

I received tons of compliments on this dress! The dress is made of great quality and it shows.  The dress is not shiny like it appears in the photo; it has a nice texture.  It has a black stripe down the side that is not shown in the picture on the website.  I paired it with black heels for an evening wedding.  

I wore this dress to a formal event and lost count of the number of compliments I received. The color is stunning and the dress was true to size.  The only con was there was some pilling along the sides. Rent it if you want to turn heads :-).

This dress has a gorgeous color and surprisingly comfortable fit. Their is a liner on the dress, so if you're in between sizes, probably best to go up a size to avoid the pulling of the interior lining. 

As previous reviews stated, the fabric is pilling from wear

The dress photographs so well and made me feel gorgeous! I have a small chest, but larger hips and the dress fit like a glove. It is thicker fabric, which did tend to be a little warm for a summer wedding. 

My mom is NOT the girly dress-wearing type (she had changed into her "comfy" sandals by the time of this photo), so I knew renting would be the way to go for her mother-of-the-bride dress for my wedding. We're almost the exact same height and weight, she just has a larger ribcage than me, so we ordered her a 6 and 8. She ended up wearing the 8 because it was a little more comfortable, but both sizes would have worked. The top was looser on the 8 but she has a more bottom-heavy shape. Overall she said she got SO many compliments on the dress and people just raved about it. Highly recommend!!

I loved this dress! The color was beautiful and fit was flattering! My only complaint was that I had to adjust the top to avoid showing "side boob".  I probably could have worn a size down, but they were out of it, so the larger size allowed me to dance! It runs just a touch large in my opinion. Elegant, classy, and beautiful blue jewel tone!

Loved this dress from beginning to end - comfortable and beautiful - lots of compliments through the night and even later!

Great fit! I received tons of compliments. 

It was a little baggy in the hips  but I have an athletic build so someone with curves could fill it out more. There was a little fraying on the sides near the bottom, but they were barely noticeable. 

I got a lot of compliments, both in person and from photos.  It photographs really well!  I ordered sizes 6 and 8.  Normally I'm a 6 but it was way too tight.  Even the 8 was snug but it fit.

OMG - the color was fantastic, the material is thicker - and doesn't show lumps and bumps and it fit like a glove.  Loved everything about it!

Nothing gives your ensemble a formal upgrade like a bold, cobalt blue dress. The thick, draped fabric keeps the color and cut from looking cheap - trust me, this dress is nothing but classiness and elegance. The cut is formfitting without being uncomfortable and the length allows the dress to teeter between cocktail attire and black tie with ease for that event you're "unsure of." 

I normally wear a 0/2 in dresses and tried on both, but ended up wearing the 4 as I have a larger rump and the 2 was just a wee bit too tight for a wedding. There is no stretch in this dress and while it runs true to size, I'd order a size up as your back-up. I received compliments on this dress all evening and it was easy to dance and move around in - though, don't expect to take any long NYC strides as it's a bit tight around the legs/knees. The dress is a heavier fabric, making it perfect for the fall morning wedding I was attending. Also, you can't really see in the photos, but there's a solid black line - very tuxedo like - down each side. All in all, amazing dress that I'd happily recommend!

Definitely doesn't run big, so I went with an 8 as I always do with dresses that are fitted at the hip (I'm usually a 6 with a full skirt). This dress made me feel like a million bucks! It has an expensive look and brings the right drama with the texture, color, and one-shoulder style. I felt like Michelle Obama, and to me, that's high praise! I naturally stood up straighter and held my shoulders back because I felt so confident. Love!

I used this dress for a November Wedding --perfect for the fall. It was a little big on top but fit fine on the bottom. Great fabric,  held well for the nite and thru dancing.  I suggest using a  strapless bra . I took a gamble  on this dress since it didn't have much reviews and I am glad I did. The dress totally stood out. Loved it!!

The dress fit perfectly , I did not need to wear a bra which is a big deal for me because I HATE wearing bras for formal nights out - it's just one more thing to worry about. The dress fit great in the waist , slightly difficult to do stairs up but that's because I am short and the dress fell right below the knee. I also had to work a little to get the skirt down after using the restroom. I wore this for a formal Indian wedding in Naples Florida . I received many compliments on the style, color and over all look :) I felt great ! Only issue was the first one came smelled a bit but RTR shipped out another the next day! 

I loved the cut of this dress, as well as the black accent stripe on each side. I wore it for a wedding ceremony and wanted to keep it on all day!

I rented this for a university fundraising gala. The color is beautiful and the design was flattering to my square torso. I was able to comfortably wear a strapless bra. I got several compliments on this dress throughout the evening.

this dress exceeded my expectations! I  wore it to a cocktail party for a fundraising and I got tons of compliments all night! everyone said I looked so elegant.    I'm usually a 00P and the 0 was just right one me.

thank you Rent the Runway!!! I felt like a supertar!

The dress was stunning and fit nice and snug. The fabric is thicker than it looks and very well made. The red hanger loops stuck out a few times.  But it was worth it. I received so many compliments all night long! 

I'm between an 18w and a 20w. The 18w was too small on me. The 20w just fit on the bottom and was a bit big on top (and I'm a 42ddd top). The material has NO give so be forewarned. That said, I thought the cut was flattering and the color truly is stunning. It's a beautiful dress. 

True to size, although the label says 14 and not 14W. No stretch and a slightly cranky zipper. I am a 36G bust and it fit me fine. Hits just below the knee which is great if you are north of 29. Gorgeous, bright, lustrous fabric with a lot of body and good drape that held up well over many hours. Boned bodice so no need to wear a bra (although I did wear a strapless bra).  It was really a show-stopper. We arrived early for the ceremony and walked through the neighborhood to get coffee in bright sunshine. In my dress and all-gold accessories, I got a lot of smiles from strangers! I felt like a starlet. 

This super sleek cobalt jacquard sheath is a go-to for your next cocktail or even black-tie event. The snug material fits true to size with structure that makes it easy to go bra-less or opt for a strapless bra if necessary. For backup, I recommend sizing up if you're curvier and down if you're smaller framed. At 5'7", the dress hit at about my knees. I really love intricate pleating and effortless draping of the one shoulder. To accessorize, go for delicate earrings. 

This was my back up dress for a work semi-formal. I ended up wearing it because the color was so vibrant and the subtle pattern of the fabric was fabulous. The black stripes on the side made it an easy choice to wear black pumps and clutch.  Was very pleased with it. Didn't need to wear a bra because the top was snug and fabric thick enough. Lots of compliments!!! 

This is a gorgeous color in person! It is a medium weight fabric that looked fabulous all night. The dress is boned in the front but it still very comfortable to wear. You will need a strapless bra for this dress. 

The dress was form fitted which helped highlight my small frame. This dress classy, and sexy. 

Loved this dress and got a ton of compliments on it, fit was a bit small.

This dress is gorgeous in person! The color is amazing! The fabric is a bit heavy, which makes it better for either indoor events with a lot of air conditioning, or in my case a semi-indoor fall wedding and reception. It was just chilly enough that I needed a jacket while we were going to and from the car, but it was the perfect weight when we were at the wedding dancing, drinking, and enjoying ourselves. 

Much like other reviewers have noted, I did notice some piling along the zipper line and sides of the dress. It wasn't bad, and not something that anyone was going to notice or comment on. 

It fit very well! I was actually surprised that it was a little big in the bust for me, considering I typically have issue with things being small in the bust. This might also just be because of the one-shoulder style causing one side to gape more than the other. It fit a little tight in the midsection, but nothing that a pair of spanx didn't make all better. 

I paired this dress with some silver heels and silver and crystal bracelet and earrings. I also carried a silver Kate Spade purse with me (which can also be rented on RTR). It was a fabulous dress for a fabulous evening, and I am honestly a little sad to have sent it back. 

The dress fit very true to size and the color is so beautiful in person. It's lined and made from a thicker material so I'd definitely suggest renting it for an inside event if you live in a hotter climate. I also noticed the zipper was on the right side instead of the left. My only con is that I couldn't keep it lol. I received so many compliments, move over lady in red! 

I rented this dress for my local political party's annual ball and it was perfect! The color was bold and the dramatic one shoulder really stood out. It was perfect! I'd like to think the dress ran a little small because the four was almost too small for me. LOL I usually wear a 2 and it was out of the question. I took off a star bc the dress had a lot of pulling and looked a tad bit worn. I'm sure no one could tell, but it def didn't come looking brand new. I highly recommend this dress! 

It is a close fitting dress with moderately light stretch. I have never worn anything quite like and when I asked my man for his opinion - well he simply said it was a different kind of sexy for me. Increased my confidence and off I went into a night of compliments. Great dance to Latin dance in since your hips feel well showcased. LOL. Not an easy dress to sit in but lovely to strut. 

This dress was a a beautiful color and I love the style. It fit very tight and I had to wear my back up size (which was still tight) . The fabric was pilling and the wear of the dress was very obvious. 

Gorgeous color!  Would have preferred a regular 14 or size 12 as the one that I wore was too big.  Super comfy though and received a ton of compliments!

This was a great dress.  It's a beautiful color and style.  I wore it with gold shoes and a black pashmina scarf.  It fit perfectly except around the bust, which was a little tight on me (but would be fine for someone with a smaller bust).  

I wanted my dress for my niece's wedding to pop and this sure did. I read tons of reviews, and kept coming back to this one.  So many complements. I told EVERYONE about RTR! Pros: great color, great lines, great fit. Loved the one shoulder.   Cons:  not great for dancing (not much "give"), boning on right side kept sticking up and ruining the look of the top. Also, dress was a bit worn at the top of zipper.  I would wear again to a cocktail event with no dancing. An amazing dress if you want to look amazing!

I wore it to a black tie optional wedding and got several compliments! The blue looks great in pictures! 
I got the 4 and the 6, I ended up wearing the 6 even though the 4 fit well. On the 4 the zipper seam was a little torn and someone clipped the stitching that connected the slip to the skirt so it was showing in the bottom. I tried small safety pins and double sided tape but ended up just going with the 6 because it looked better (pictured in the size 4). There is a little bit of fuzzy fraying, but you don't notice it unless looking for it and didn't show in pictures.


I loved this dress! I rented this dress for a closing ceremony for my husband's fraternity conference. I
rented both 12 and 14W. I wish the 14 was just a regular not a wide. Other than that it was perfect, very comfortable and flattering even after 4 days of eating bad, we had been at Disney for the week. Wish I could buy it.

Fits true to size and is a great color! I loved the style and was perfect for a summer wedding. Both dresses I ordered showed pilling and signs of wear but wasn't a deal breaker. Comfortable dress and fun to wear only downside was there is no slit so it's tough to walk in walk in at times and try to pull up to go to the bathroom. 

If ordering, this dress is sized very odd. Would recommend ordering one size up since the size on the tag doesn't seem to reflect what it says. 

This dress fit extremely well. The dress I received had obviously been worn quite a few times and was pilling quite a bit. Luckily, this was only noticeable if you looked closely.

Color and style was lovely, elegant, and timeless. Fit was a little tight around my waist but I'm a little fuller in the waist. Only reason I didn't give it a 5 star (wish there was 4.7) was that the material was a little different than what I expected (thought it would be a silk organza but more of a thick, patterned, cotton) but still pretty. And zipper stuck.  All in all, a winner!  I really liked it a lot. 

Good news first: I received NONSTOP compliments about this dress all night. It is a gorgeous shade of blue and great silhouette.

Bad news: All of the compliments actually surprised me because I started off the night being very self conscious about this dress. As someone mentioned in a previous review, the dress I wore had definitely seen better days. There was pilling around the seams and the blue seemed like it would have been a more vibrant shade in its earlier life.  I thought it looked pretty shabby, to be honest, but I didn't have any other options at that point. Also as mentioned in another review, there is NO slit in this dress. It is EXTREMELY difficult to walk up and down stairs, so if you know you're going somewhere will you be constantly walking or dancing, this might not be the dress for you.

Dress is pretty true to size, but I do recommend ordering a smaller size. Slip showed a little, but it wasn't very noticeable. Lots of compliments all night!

It fit wonderfully and looked amazing!  Tight enough at the bust to not have to wear a bra but loose enough in the waist to not feel constricting, and I could eat dinner without feeling breathless.  It was difficult to take full strides while walking and get in and out of the car the way the skirt fit at the bottom, but it wasn't a big deal, my boyfriend just had to walk slower with me.  I also noticed that the material seemed a little misaligned in the front; the bottom fold didn't lay like I thought it should, so I was messing with it a bit throughout the night.  I received a lot of compliments on the style and color from both women and men!   I wore nude pumps and gold jewelry, and they were stunning.  Since it was my first rental, I forgot to get a good pic of the dress, but I tried to crop a group photo as well as I could.  I highly recommend this dress!

A very vibrant royal blue - I received many compliments on the color! It has a side zipper so you may need assistance getting in and out of the dress.  Thicker type fabric with an inside lining.  Very comfortable fit. 

Dress is gorgeous but of a thicker material than appears.  The size 8 I put on had a slight tear along the zipper.  As mentioned by someone else, the fabric catches easy as it is woven versus something like a silk.
