Perfect for formal wedding!

I wore the 0R as the dress had some stretch to it. I have a big chest so it was a bit snug on my breast but not uncomfortable. I wore a regular bra and simply tucked in the left side strap for it not to be visible. Very pretty dress although it may seem a little boring. I think this dress is stunning for those with a hourglass/curve figure.

Gorgeous flattering dress

This was a last minute backup choice since my original choice was not available, but it ended up being a beautiful dress. The fabric is very high quality and the ruching is very flattering. Highly recommend for curvy babes.

Beautiful Gown

This dress was amazing. It fit amazing. I love how the dress want super tight but fit like a glove. It was long enough that you could wear flats with it to be comfortable. If you wanted a longer fit the 8 Long would be perfect for heels.

Feel elegant AF & comfy!

Amazing dress! I do have a broad chest and couldn't have worn a bra with it but I didn't have to because the fabric is so nice everything stayed in place and looked amazing. I don't really like my armpits showing so it hid that area that I'm not fond of. The mermaid style makes you look curvy, which I'm not, so I loved it made my butt look great. It is long but was perfect with my 1.5-2.0 heel. I got so many compliments, must have for a formal wedding!

Felt Like A Princess

This gown fit like a glove and was perfect for the formal event I attended. I truly felt like a princess in this beautiful dress, and it reminded me so much of one of Princess Diana's iconic ball gowns. I could only get the size I needed in a regular length so was concerned that the gown would be too long. I'm only 5'3" but with 2 1/2 inch heels, the length was actually perfect! I would definitely rent this beauty again!!!

Great dress, comfortable material and fit.

Wore this at a black tie wedding, late September. The dress is thick enough if the weather is chillier. You can’t really lift your arms because of the way it rests on the shoulders. Overall, it is true to fit and comfortable to wear for many hours. Highly recommend!

Lot of compliments. I felt elegant.

Fit was perfect, length was great, style was on point. Best of all, it accommodated my 44DDD bust line and the length was great with my 5'8" frame. I'd suggest kitten heels, though. The sleek lines helped to smooth my belly, the mermaid skirt was very cool and retro feeling. I also liked the faux off the shoulder style which helped hide my upper arms while but was still summery. I brought along a stole, but I didn't need it. I haven't felt that good in dress in a long time. I'll be renting more of this particular designer.

This dress is so comfortable and flattering. Compliments all night!

I usually wear a size 6 and the 4 fit like a glove. I’m 5 foot 9 and 130 pounds. I needed the long. I wore this with red sparkly heals. I’m 46 and my program was being honored at a charity gala so I had to look professional. Perfect dress.

Wore this dress to a daytime black-tie wedding in the summer in Texas. It was super stretchy and fit like a glove. The thickness of the material wasn't heavy and hot. Would definitely wear again!

Amazing Dress

I'm short (5"3') and my 3in heels kept this dress right up off the ground. The off-the-shoulder parts stayed in place all evening. It was hot, raining, and humid out but I stayed comfortable. This dress hugs everything just right with rich fabric. There is no stretch on main fabric. I am large busted and there was enough space in the chest without it feeling tight or spilling over/out. I will definitely be renting this one again in the future.

Absolutely flattering and comfortable

Extremely comfortable and so flattering. I am a little fluffy around the middle, wouldn’t have known in the dress. Wore it to event on cold Feb evening and didn’t need a coat because of the fabric so lovely and full. Was not overheated either. The pictures don’t do it justice. The flare out at the bottom is divine and falls just right. I used bra pads from a sports bra for the top because it doesn’t come with reinforced bodice, but a strapless bra or pasties would likely have worked fine I just didn’t have one.

Black Tie Ready

This is a very conservative, safe dress to wear for a formal event. I should have sized down, but the dress was not available. It was the perfect length with a 3 inch heal. I found that the sash around the shoulders was too loose and I should have used fashion tape to get it to lay properly. It was a very comfortable, flattering dress and was easy to dance in.

This was my back up after my original dress failed to ship. I was very happy with it.

The dress is Nicely lined- did not need spanx. Comfortable. A little long with 2 inch heels but not a tripping hazard. Felt great all night.

Fabulous fit!!! And it was my backup gown!

I got stopped on the street in NYC by two women who thought this gown was just beautiful and it was!! So comfy and it was so easy to get in and out of the car (which sits low to the ground). The color was a deep blue and the asymmetrical neckline was stunning. I’ve rented so many gowns over the years, but this one was a winner. My first choice was mis-sized and huge, so I had no choice but to wear this one. I picked it out so quickly and I just loved it on. You won’t be disappointed.

Lovely and simple gown

I got lots of compliments on this dress, and I felt great in it! If you, like me, are hourglass-shaped, be aware that fitting your bust and hips may mean it's a little bit loose in the back, but it wasn't so much I felt insecure in the fit or that anyone else could see. Works great with a strapless bra, and genuinely as comfortable as I'd expect a formal gown to be.

I wore this gown for my son's wedding and it was perfect style for a summer outdoor wedding.

I could not get the 16R so I chose the 16L. I had to hem tape the front of the gown. It was comfortable to wear all afternoon and evening. I would definitely use Rent the Runway again. It was a positive experience.

Comfortable and stylish

Really can’t compliment this dress enough. Really comfortable. Wore to the Tony Awards and got lots of compliments and felt great in it all night. Loved the neckline and the mermaid kick at the bottom. I’m 5ft 7 and wore a 3 inch heel and it was a perfect length for walking in. Would love to buy it as feels so wearable and for many things and quite classic in fit.

Comfortable and classy

I usually wear a size 12 and the size 14 was the one available-it ended up being the right one. It is form fitting without being tight and has ruching on the side. This makes it very forgiving and I decided to forgo shapewear (plus!!). I would recommend for girls with curves!

Gorgeous gown

I wore this gown to a ball and it was so elegant. Firstly, it arrived early which was great as I was worried it wouldn’t fit (a back up size was unavailable). I removed the dress from the bag, it had no wrinkles and was in perfect condition. The material was stretchy and clung to all the right places. Just a beautiful dress. ❤️

Perfect for black tie Mardi Gras event

This was my first RTR & I was nervous about delivery timing & fit. Delivery was on time (2 days before my event) & fit was perfect. I do wish RTR had more designs for bustier women that were not deep plunging necklines & cut-out midriffs. In a typical year, I have 2-3 formal events & try to rotate what’s in my closet, I’ll definitely add RTR to the rotation.
