I'm 5'5" 110lbs 34C and felt the 0 ran large. The straps in the back had to be pulled so tight and high in order to prevent the bust from slipping; it just didnt look right.

Beautiful color and I want to live in the material for the rest of my life!! The length is perfect for you long legged beauties out there!

The straps were to long and I had to pin them since I'm petite 5'1". I used fashion tape so I wouldn't have a mal function. All in all sexy and classy!

i LOVED this dress! got so many compliments. classy but sexy at the same time. 

I wore this dress for my backiversary (I had back surgery many years ago and like to celebrate annually!). I love wearing a dress that shows off my back and this was the perfect selection! I felt classy, sleek, sexy, and beautiful. It also happens to be the same designed Jason Wu dress Emma Stone wears at Seb's at the end of La La Land! My only slight complaint is one of the straps had some wear and tear, probably from numerous wearers. It was also a tad difficult to hook into place, but that's more user error haha. Once it's hooked you're good to go for a truly fantastic night full of compliments!

Pros elegant in front and sexy in the back.  Cons - could feel too open in the back.

I saw this in store and *had* to rent it. It was a size 8, way too big for me, but when I tried it on, it actually fit in every area except for my chest. (Damn you, small chest!) I decided it wasn't somethign a little fashion tape couldn't fix. So I rented it, wore it to watch Hamilton in SF, and felt like a million bucks.

This simple , elegant slip dress was perfect for a auction party I attended. The back is stunning & sleek. It was a tad loose on the sides so I would recommend som sort of adhesive. 

I felt amazing and wish I could keep this dress forever!!!

I loved this dress! Not too short but a lot of side boob. The color and fabric make this a hot number :). 

Beautiful and vibrant! The material is amazingly comfortable for such a fitted dress and makes you feel like a million bucks. I would recommend wearing your true size, as sizing up may be a little loose in the bust area as it was for me. Pair with a strappy heel and some simple accessories for the perfect look!

Beautiful cobalt color with a lovely sheen.  A fashion forward dress great for a formal occasion or party. This runs true to size and has a padded bust providing great shape. 

I loved this dress. The side boob, as many will tell you, required some attention. My fashion tape ended up not working, but keeping good posture all night seemed to do the trick! It ran a tiny bit large, but it was manageable. I always worry that dresses will be too long on me, but this fell perfectly. Tons of compliments, I would definitely wear it again!

This was actually a replacement dress that I chose at random when one of my backup dresses wasn't available. 
I saw originally worried about the length of the dress, seeing as I'm short, mid length dresses usually make me seem squat. This dress hit perfectly though! 

I have a curvier figure and it hit in all the right places. 

Cons: I felt like my boobs were popping out so the use of fashion tape was a must. 

Otherwise, a beautiful dress for a lovely evening. 

I rented this for a wedding and loved wearing this dress. Warnings on the fit/ construction: you will show a lot of side boob, I had no tape but just went with it after a few drinks.... Also, the cross straps were poorly fastened and kept popping off when I turned and almost gave the everyone in my pew at the church a show-- luckily I was able to pin it at the reception and was good to go. 

Warnings on the style: you will be the classiest, sexiest woman in the room, especially from the back-- eyes will be on you, beware! I wore this with matching satin d'orsay pumps and it was killer! Not for a shy lady!

Also, I recommend no undergarments or sticky boobs-- would deter with the slinky fabric. Oh yeah this dress so wrinkled when I got it, luckily wrinkle release and humidity unkinked it in the nick of time.


If you aren't willing to show some skin, don't rent this dress. The back is completely open and there is some major side boob. I really liked the fit around my torso. 

true to size. I would NOT recc for A/small B cup. looked great - so many compliments. 
Im a 6 usually, but an 8 fit great. the waist is a bit smaller, but other wise true to size. no bra just some fashion tape - the inner bra helped with a little padding. i was worried it would be too long. hit right above knee and sexy everywhere else that the length classed it up. Im 5'5- 140 lbs, 36c 

The color and fabric are to die for and very high quality. The dress drapes everywhere I wanted it to, and I LOVED the built in cups! The only reason for the four stars is as other reviewers have said, it's pretty baggy for those of us with smaller bra sizes. I wish the back straps were adjustable- I ended up having to pull it into a halter and safety pin mine at the base of my neck (I'm a 34B). Otherwise it was a classy and sexy dress! 

Very pretty color, and the thin straps on the back are so cute. But the front, although padded, is a bit loose and doesn't have any support. Couldn't even really wear tape as there's lots of side boob  showing and would show the tape. If you are comfortable with no bra and side boob, it's a really pretty dress. 

I loved this dress! I don't normally wear form-fitting dresses, but I tried this on in the RTR store in Chicago and fell in love. The material is thick and doesn't wrinkle easily. 
I did have to use a lot of tape to avoid excessive side-boob, so it you are shy, this might not be the best option. 

It fit like a glove, and the back detailing is really stunning.

Recognize this dress, anyone? That is because it is the same dress that Emma Stone wears in the 5 years later scene in La La Land, a movie with fantastic costume design. I loved this dress. I have larger breasts for my size and I definitely had some side boob happening. It was slightly tight on me and slightly skimpy but for a sexy date, it is appropriate. I would absolutely recommend it. 

I wore this for a wedding and it was absolutely gorgeous.  After reading some of the reviews I was slightly concerned about "side boob", but i think it showed just the right amount of skin!  The dress was very classy as it covered my chest and went down to right above my knee, but was still very sexy as it showed My whole back and was fitting and sleek!  I have a B cup size, so that definitely helped with not showing too much cleavage and have a tall slender body type.  It was absolutely perfect for what I was looking for!  I would definitely recommend!

Perfect cobalt blue, I was a bit worried about the fit at first but once I tried it on it worked fine. I am very flat chested so I did not fully fill out the upper part of the dress but the back detail was so pretty it didn't bother me too much. However this top would be ideal for a larger chest. Surprisingly didn't wrinkle when I packed it or when it came in the mail. 

Don't forget the steamer and the garmet tape :)

I loved this dress. It was very sexy in the back, but conservative enough for a wedding because of the front. The color is simply gorgeous and definitely received lots of compliments on the dress. The neckline on it is also beautiful and you don't need to wear it with a bra because of the cups built into the dress. The only slight negative was that the straps were so long, but I had my fiance twist the back straps for me so that it looked more like a racer back and fit more tightly. 

Fabulous dress, fits true to size.  I would recommend sizing up for larger hips as it does not have a ton of room in the skirt.  Love the built in cups, which allowed me to wear the dress without a Nubra.

I really liked it, except you have to wear a backless bra with it. 

I owe this find to the staff at RTR in Georgetown who insisted I should try it on.  I fell in love with it the moment I tried it on.  I'm normally a 4 but the 6 was the only size available.  The material is luxuriously smooth and silky.  The dress has built in cups to add silhouette so I didn't need to wear a bra,  though you'll want to use double sided tape to secure the dress and avoid potential "side boob".   This dress is the perfect length and just the right amount of sexy.  

I should have ordered a size 4 but even with the size 6 I looked great and received a lot of compliments! The fabric is beautiful and does not wrinkle easily. 

The dress runs kid of small especially if you have American bra sizes....... The dress overall looks extremely sexy and elegant but might be a little too exposed. 

This dress was so pretty and I'd really hoped to be able to wear it for NYE, but upon trying it on, it didn't fit properly. The top was droopy in a way that two sided tape couldn't even fix. More specifically, I'm busty up top and I felt like I was coming out of the sides. It may work better on a more athletic build. Another note: the snap holding the strap on the back was a little loose too. I felt like if I danced in it, it wouldn't stay fastened. 

The fit was a bit larger than average for me at the top. There are padded cups sewn in, but they felt large on me. The fabric feels great. Very classic 

Very odd fit in chest. Has weird pads that make it gape at the sides and causes weird look from front and major side boob. Couldn't wear to my event. 

I am 5'3" and have a short torso and long legs. The cut of this dress just didn't work for me due to my short torso. The bust area puffed out and make my boobs look pointy and far apart. Beautiful color, though!
