So stunning and flattering!

I loved this dress, it hugged me in all the right places and looked fabulous in pictures. I got a ton of compliments all night. I procrastinated on picking a dress and by the time I did unfortunately my size, a 4, was out so I went with a 6 which was a little too loose but worked out fine. I wore nipple pasties and would definitely recommend, it’s a very thin dress.

This dress was perfect for an NYE wedding guest. Wore Cakes instead of a regular bra since the back is open. Fit reallly nicely and got a ton of compliments!

Super flattering for black-tie wedding

Perfect length to still show off fun heels, true to Reformation sizing (I have a wide rib cage so size 6), and very flattering with the scrunching fabric around the stomach area. Don't have wide hips but this dress had a great shape to give me a bit more curves around the hip. Tons of compliments! Would recommend to anyone, but especially with athletic build.

RENT THIS DRESS!!

Absolutely LOVED this dress! I felt so great in it. Very flattering in both front & with the open back. Both the 2 & 4 fit me very well, honestly wasn’t able to really tell much difference in the sizes but 4 just felt more comfortable to me. I was able to wear a sticky bra with it without any issues. Shows lining of underwear so I ended up going without. Also will show any spills on it, even water so be careful. But definitely worth the rent! I got so many compliments

Super flattering and comfortable

The open back looks super cool and the overall fit hugged nicely but not too tight. I sometimes have trouble with more fitted dresses with a thinner material fitting correctly, but this hit all the marks. I wore it to a formal/gala-type event. Also, so comfy and breathable!

GOT SO MANY COMPLIMENTS

This dress was absolutely beautiful and I loved it. I would rent again in a heartbeat! The only thing that I would do differently is get special underwear for it… I wore a seamless nylon pair (I was on my period—otherwise I would’ve gone without underwear) but a sliver of the underwear still showed through the back cutout. I kept adjusting them and folding them down, but they just moved back when I walked. All in all, it was an AMAZING, classically beautiful, timeless dress. I felt so pretty 🥰

THE Perfect Dress!!!

Truly have never felt so good and confident in a dress. True to size and fit like a glove! I also am larger chested (DD cups) and felt secure the entire night dancing and everything. I received so many compliments on this dress and am now seriously considering purchasing it because of how flattering it was!

Beautiful Dress

This dress was perfect for the wedding. I’m typically between a size 8-10 and I wore the 8 (5’6”, 160 lbs, 34DDD). The fabric was light and comfortable. I was nervous about not wearing a bra, but I think it ended up being okay with pasties. It did show water stains quite easily, but that was towards the end of the night so I didn’t care. Got lots of compliments and would love to have bought this one!

Sleek and Simple

Once I had a chance to figure out that the back was a cross-strap, then I finally got a hang of this dress. It feels like water when you put it on. Seriously, it was such a light fabric that I felt like I was able to easily move around in it. An easy and fun wear for a night out.

Loved it, but it's high maintenance

Fit perfectly and really gorgeous when on. The fabric is super silky and has a lot of static cling...it shows any imperfections really easily (even if you just get a drop of water on it...it will show the outline when it dries). Also, required sticky tape for a bra. I did love it but it certainly was a dress I had to be constantly aware of while wearing

Beautiful BUT…

I loved the dress! It was beautiful and I got so many compliments. But it was EXTREMELY thin. Satin gowns are notorious for this, but this was remarkably thin. You can see a lot of texture through the dress (not just nipping out but full areola visible). I normally tape my boobs for backless gowns and you could see all of it. I ended up wearing silicone nipple covers and even though they were extremely thin on the edges you could see a slight ring around my breasts. Additionally regardless of wearing the thinnest no show underwear, you could clearly see the outside from behind. Be prepared!

Cute, but shows everything

I liked this dress, but I wish I could have worn spanx with it. The low back doesn't really let you do anything about that. I also spilled some vodka soda on it and the wet stain would not come out for a long time which was frustrating.

Wrinkles and too big

I wanted to love it- but it was just a little too big. The biggest issue was that I couldn’t wear a bra, and one was definitely needed with that sheer material. I tried using tape, but you could see the tape too. It was wrinkly, and I wish it had a slit in the leg. Not a fan.

This dress was everything! Fit like a glove and wore nipple covers underneath. It does show everything though so if I was bloated that day I might have been self conscious.

Sweat Stains

Reminder -- just in case you're like me and haven't worn light grey silk in a minute... when it gets wet, it turns dark gray. So don't sweat in it. The fabric is lovely and in a normal 72 degree room you are probably going to be fine. If you're trying to rock it on a hot summer day... think twice.

The grey dress was perfect for the black-tie wedding I attended. I'm only 5'2" and it was floor length on me, but it still looked great. So glad to have it for the 8 days since I was traveling...

Was obsessed with this dress, so silky, sexy, and even modest at the same time. It was perfect for a formal rehearsal dinner, and really comfortable. I was surprised by that it wasn’t too tight in the hips/ stomach. I was 4 months pregnant when I wore this, and only went up one size and it was plenty big.

Bold dress (in a good way)

For silk, I was so surprised how well this dress fit, although I didn't feel like it was appropriate for the event I was going to, so didn't end up wearing it. A great option for a wedding though. Loved the back but would have needed some fashion tape to get the top to look the way I wanted. As others have noted, it's a tight fit over the head when putting it on, so dress first, then do your makeup.

Gorgeous slip dress!

I did not get a great photo in it, which is sad because I felt like an angel all night. I did not wear underwear due to panty lines and wore sticky boobs in the front. This dress is beautiful and true to size, I went with the size 0 and didn't even need to try on the two. Would rent again, many times over!

Love love love

I got a million compliments on this at my kids' school benefit gala. Material is super thin and very breezy. Static guard a good idea. Important: it is VERY snug to get on around your head (think turtleneck), so I had to put on makeup after getting the dress on.
