Classy + fun

Loved this dress! Wore it with an oversized scarf in January. Super flattering (more so than the picture shows). A little restrictive in the legs so wouldn’t recommend it for dancing, but otherwise loved it!

My absolute favorite dress. I received so many compliments on it. Sad she had to go

I’m 5’1 and it got great. However it was tight around my legs. In order to go up stairs I had to lift it a bit

This fit was everything I wanted. It was stunning and the earrings (RTR) truly made the dress pop more. I would definitely rent all again.

Great choice for black-tie optional

I wore this to a school gala and could not believe how much I loved it for how simple it looks. The neckline and strappy back make it interesting and the material is comfortable and elegant at the same time. Only bra possibility would be sticky things, but I skipped them and it worked out fine! Would rent it again.

Great rental

This fit perfectly and the adjustable straps are a big help. I’m usually a 4 but chose a 2 here because it fit well. It’s also perfect for cooler months but I didn’t sweat too much dancing in it.

Surprise Sophistication

This dress was my last choice when originally picking out options. Once I tried it on, it was my first! Wore to a gala. The fit of the dress made it standout even though it seemed plain on the hanger. The slight bunching around the waist and the asymmetrical neckline were fabulous. The dress allowed my hair and makeup to pop, brining the full look together! Even looked into buying this dress. Only wish the dress length was a tad shorter on me because of my height, but this was not too big of a concern.

gorgeous dress! so flattering!

Wore this dress to a wedding and it was wonderful! Such a nice fit and the open back was very flattering! The way the dress lays in the front really helped to conceal the stomach area.

Loved this, got lots of compliments

This dress was beautiful and well made. Wore it to my brothers rehearsal dinner and received a lot of compliments. It runs a TINY bit on the smaller size specifically around the rib cage, so if between sizes, suggest sizing up.

Very flattering!

This dress is very flattering and perfect for any event with cocktail attire. I do love the color and the ruching is very flattering. If you are a bit curvier in your hips/bum then I would size up - the top is adjustable and there’s really not a lot of give in the lower half. Luckily once I put some spanx on the bottom half felt a lot better.

Elegant and timeless

while an assuredly elegant and timeless style that gets compliments, the dress is completely unlined all throughout - single thin layer of satin for the exception of the ruched detail in the bodice. as a result you can't get away with going braless even if you normally would with a backless dress. ideal for above average height - overall length as well as the length of the bodice were too long on me, resulting in an unflattering fit for a petite person. finally, as others have mentioned, the hemline diameter is very restrictive and seriously limits your range when walking or dancing.

Safe choice

This is a safe choice if you don’t want to be too flashy. There is not much give; I would have felt more comfortable in an 8 but they didn’t have that size. The only reason I am giving it 4 stars is the quality. I would have maybe paid as much as the rental was to buy it to feel like it was worth it.

Great Wedding Guest Dress

I liked this dress! It was nothing crazy special, but the neckline is very cool and it fit fine. It wasn't as tight as I wish, but I have a very thin frame. A size 0 was not available at the time. Comfortable and appropriate for an outdoor wedding in Florida in November!

Fun dressy wedding outfit

Great dress- the blue satin color really stood out. The top part of the dress was a little loose (I'm a 34B) but it worked out fine. Would recommend for a summer wedding.

Very Elegant

Love this dress! It gives sophistication and class. Paired it with gold, strappy, kitten heels, and felt amazing. Love the fit. My only critique is that there is no slit. That made it a little snug at the bottom, which made my steps a bit smaller.

Classically sexy

This was the perfect sleek dress for a formal/cocktail wedding. I felt classy, comfortable and the low back was a sexy touch. I didn’t feel the need to steam it as it really didn’t hold wrinkles, which was nice for travel prior. I used breast tape and the adjustable straps worked well to keep the top flush.

Trust the reviews - best dress ever!!

This was an AMAZING dress - I normally wear a size 2, this fit perfectly. Fabric looked like a much more muted, dark navy than some of the photos on RTR. Back is very low - I wore Cakes silicone covers instead of a bra and had a super comfortable night feeling amazing!
