Great dress for a holiday party!

I wore this dress for my holiday party at work. It was very comfortable and I was very glad I chose this dress. Most of the time I wear an 18W in dresses from this site but this dress is pretty form fitting so I wore the 20W to feel more comfortable.

Super flattering, pretty, and comfortable

The dress I originally got didn't work, but luckily I was going to Vegas, and could exchange it at the store there. When I saw this dress on the website, I didn't think I would like it. But I tried it on in the store, and it was amazing! The lace was gorgeous, it fit perfect, and was super flattering. I was comfortable all night. I will rent this again!

Very comfortable!

I unfortunately didn't get to wear this dress because the lace at the too was noticeably ripped and they were unable to get me the same dress in time for my event. That being said I would've loved to wear it! It was very pretty, comfortable and gave my body a nice shape.

Wonderful dress.

It was a gorgeous dress but it was really big, I had to pin it for it to fit.

Another hit, sexy with a little elegance

It was very comfortable, stretchy enough for wider hips. Fitted at the waist. Over all it was a pretty dress. Perfect for the concert with the shimmering details

This was a last minute switch. Original dress did nothing for me and RTR replaced it with this.

Dress fit perfectly everywhere except the bust. I am rather busty and the dress was loose. Not very forgiving in stomach area, but a pair of spanx really helped. Got several compliments and hubby absolutely loved the way the dress looked on me.

Didn't end up wearing but beautiful nonetheless

Got three dresses for a gala event; this dress, while beautiful ran VERY large on me. It was very gappy in the top and just fit awkwardly. In a smaller size, it would've been gorgeous!

Fitting in a dress that showed all my curves

The dress fit pretty true to size. The only issue I had was it was really lose in the bust but I added a belt and you couldn't tell. I got so many compliments on the dress.

Lovely lace

I think this dress would be lovely on others but it didnt work for me. The lace detail at the top is delicate and especially pretty. The sheath shape and seams through the torso make for a slenderizing fit. Fits true to size and is form fitting.

Felt sexy

The dress was very comfortable and the fabric was forgiving. I slipped into it and felt like I was wearing pajamas. I wore it with a black demi bra with straps but because of the lace and seams, the straps aren't visible. I got a lot of compliments and was able to sit, move, dance, and enjoy freely. I could have worn the size 18 and it would have been fine. The bust would probably have fit better, but I opted for the comfort and moveability of the 20. Because I'm a true 18 and wore a size up, the bust did feel slightly loose but it wasn't too bad.

I was complimented all night and felt absolutely beautiful for once.

The fit was big. I was surprised. I ordered a 16 and a 20 (because the 18 was out of stock for when I needed it). I was thrilled with the dress overall. I was complimented all night. I am a busy mom of 2 young girls, doing my hair is a treat and sweatpants are a norm. I felt absolutely beautiful.

It was very forgettable.

It's was uncomfortable and it showed large gap under my arms, right where my fat poked out. Despite a few removable stitches by my seamstress sister they remained. Won't rent again.

Tons of compliments on this dress!

I rented this for an office holiday party at an upscale restaurant. I've gained some weight lately and my 14's have been very tight, so I looked for a 16 to rent, and it turned out to be HUGE on me, but it ended up working out fine. I used fashion tape to gather the back and covered up the "bunchy" part under a silvery gray blazer. No one knew the difference and I got lots of compliments. The best part was, in spite of all the beautiful women in cocktail dresses, my husband couldn't take his eyes off me! I recommend this dress; would definitely rent it again if it came in a smaller size. (Sorry photo doesn't show much of the dress... our event photographer just did head shots.)

Wonderful Vegas weekend with two of my three daughters and son-in law.

dress is not as "glitzy" as it shows in the rent the runway photo. fabric was nice -- fully lined. I would have liked it a little bit shorter and probably should have gotten a 14w for a better shoulder area fit. All in all it was a lovely dress.

I wore this on Christmas.

I loved this dress so much! It was stretchy and felt so comfortable! It had different textures and was truly unique. I received so many compliments on it! I normally don't wear Women's sizes, so that might be why I felt the dress ran large, but when it comes to sheaths I try to order up because I have huge thighs/butt. This dress fit really well despite that problem area - I had to wear a thick belt around my midsection because it was a bit large there. You could easily wear it to a wedding with cocktail attire or other evening event. The center fabric is a sparkly, shiny silver and the sides are a softer, yet still sparkly black. There is beautiful lace detail at the top of the shoulders. Because I am short the dress fell just at about my knee, but that's the look I prefer. I highly recommend this dress!

Complimented all night long! Felt like a million bucks!

After the first dress I rented didn't seem to fit right I called and the RTR stylist was more than helpful making sure I would find another dress I would love! She sent this beauty which I had my eye on but with no reviews I was hesitant to order! It arrived the day before my husband's holiday party in mint condition! Since the first dress I ordered ran small I thought that might be the case in all the dresses so I ordered up. It ended up working out but it was a little big especially on top! I think in my usual size it would have been perfect! It was a cold Kansas night so I paired the dress with black tights and booties! I kept my jewelry simple since the dress was the show stopper! I felt like the black panels on the side really slimmed my waist! My stylist was so sweet and helpful! Can't wait to rent again!

Beautifully made dress, fits well, fabric is soft and very forgiving.

I ordered a different dress for a formal event but when it wasn't available at the very last minute they sent me this dress. This dress is more of a cocktail dress and I was attending a formal event. RTR staff was amazing and overnight-ed me a more appropriate dress in time for my event. While I did not end up wearing this dress, it is a beautiful dress and would b great for an engagement dinner or a cocktail party. The size 16 fit me very well. I can see myself ordering this dress for a different event. The photos really don't do this dress justice it really is a lovely dress.

Very cute but very form fitting.

I picked this along with two other styles. This was my first choice from online, but when I put it on I realized I would have to wear spanx. It shows all your lumps, because it is very form fitting. I was not in the mood to wear spanx, so I didn't wear it. However, it felt comfy enough and the color block was slimming. The sleeves are not good if you want to hide arm wiggle.

Girlfriends gave compliments. Great with statement hair.

I originally had a 20W and 18W sent. The 20W I was just swimming in. The 18W was tight in the hips, until I added shape-wear. With proper undergarments, I was able to but on the 18W without unzipping over the top of my head. I had some fat rolls showing but with the design. I didn't think they were too distracting. The dress help up to dancing and I didn't need to tug on it all nigh to keep it down.

Felt glamorous and beautiful for my 40th birthday party in this Kay Unger RNT rental.

From past experiences, I always get the next size up thinking this will be dress I'll have to choose. Not so with this beauty. It fits true to size. The lace edging is dainty and feminine. The dress fits like a glove but has a little stretch in it. I was comfortable even into the wee hours of the night. Many compliments all night.

Great backup!

I ordered this as my backup dress. It was much prettier than in the pictures on RTR's site. I almost wore it, but the primary dress had a little more "bling" and more appropriate for the occasion. I'd wear this dress in a heartbeat though! It's very flattering.

This dress made me look like a star. I was the sparkle in everyone's eyes.

This dress arrived in the time that RTW said it would. As a back up I chose the 22w and that was to big for me, but the 20w was perfect for my body. It hugged in all the right places. It had a demure/modest feel to it, but the lace gave it the Va Va Voom that it needed. It was overall an amazing dress not to short, not to long. The silver part of the dress wasn't over designed at all. In fact it was very hidden, then when I hit the light, I sparkled. I got compliments all night and it wasn't even my event. I went to support a friend and in the process I became a star. Thanks RTR for making my night truly extraordinary.

Very comfortable dress and prettier than the pictures.

This fit a little loose but it was very comfortable. It was much prettier than I thought. I did not pick this dress. The stylist sent it as one of the options when my original chose was damaged. I did not end up wearing it but it was a lovely option.

Great dress! I wore it to the symphony with my fiance.

The 22w was a bit big up top (and I wear a 46 DD), but the 20w was too tight and short. I went with the 22w. I felt great in it and got compliments all night!

Just the right amount of sparkle

This for the most part ran true to size. Initially I tried the 18W and at first I thought it fit but it looked very frumpy. I tried the 16W and it was much better. I liked the sleeves and thought the length was perfect. I am 5'7" and it hit right above the knee. Very comfy dress and I didn't need spans to hide any bumps and bulges.

The dress was beautiful and I received many complements. It was true to size and very comfortable - felt wonderful in it. I was able to wear undergarments that I already owned which included a strapless bra that came with clear straps - worked great!

Easy Glamour

I rented this as a back up dress for a fundraising gala, and ended up wearing it because my other dress was too short and tight in the rear. This dress was great - so comfortable and easy to wear. The center panel made the dress very slimming, and is only subtly sparkly, not too over-the-top, which I liked for the cocktail affair I was attending. It's a nice length, and hit me right at the top of my knee. There was a lounge area with low love seats and this dress allowed me to sit comfortably without hiking up too high. I felt great and got tons of compliments. I was very pleased with my first RTR experience. This dress doesn't seem to have as many reviews as others, but it is fantastic in person and I would definitely recommend it!!

I overestimated my size so everything I ordered was slightly big but it made it easy to eat, drink, and dance the night away in this dress. I received so many compliments on it and felt wonderful all night long!! I definitely recommend this site to you for your event!!

I wore this for a romantic Valentine's Day dinner on a weekend trip to Minneapolis!

I wear a size 16, but this dress was unavailable in that size so I took a chance. The 18 fit well and felt comfortable, even if it was a little big in some areas. It was slimming in the best possible ways, and a unique style you don't see in every store. I got compliments from total strangers, but most importantly, my future husband couldn't stop staring! This was my first RTR rental and I cannot WAIT to rent again! Thank you for making my night unforgettable!

Everyone loved the dress, couldn't believe that it was rented!

I found that it ran true to size. I would suggest wearing a strapless bra with this because otherwise you will be able to see the bra straps. I ended up wearing a black camisole to help hide the bra straps
