So dreamy!

This dress is so flattering! I usually wear an 8, and sizing up to a 10 was the right move. It’s a snug fit without being too tight. My only complaint is that the sleeves kept falling off my shoulders. But it’s a minor inconvenience for such a cute dress.

So pretty! Size up in reformation

Normally a size 0-2 but always a 4 in reformation and this 4 fit perfectly! I wore this to a Friendsgiving w below the knee boots and got so many compliments! Bust is large and rib cage area is tight but still looks really nice!

Loved this dress! I could probably have sized down but the 6 still fit great.

Back up dress ended up being perfect!

Had several issues with the original dresses ordered (zipper broken and stretched out) so this was a replacement and I was THRILLED with it. Wore to a HS reunion- it was cute and flirty but not overly dress or sexy. Wore it with white tennis shoes, but could be dressed up easily. SO flattering- and not too too short (especially for Reformation). I have a small chest, so it worked- but I think bigger busts may have issues with the fit. Wish I could buy it!

Comfy and great print

Wore to an outdoor wedding and loved it! The only issue is that it required two other people to zip it for me because the zipper kept getting caught on the fabric because of the rouching (not a sizing issue I swear! Just a composition issue of the dress). A little on the shorter side and if I wore it again I would use body glue because the sleeves were a little finicky. But I loved dancing in it and the pattern was so cute, the fit was really flattering

Girlish and fun, sleeves kept slipping

I liked this! I find Reformation’s sizing is often weird on me, but the stretchy back panel made this a forgiving fit. The only problem I had was that the sleeves kept slipping down my shoulders. Not a bad look exactly, but annoying during dinner. Had to wear a strapless bra with this.

Cute & flattering

Really cute and flattering dress. My only issue is that the sleeves would fall down off the shoulders. Would probably be better to double stick fashion tape.

Cute dress

If you're unaware this brand runs small, if you are above a 32 bust I would highly recommend sizing up one size. Normally I wear a 2 but got a 4. Cups are still fairly small but I made it work with a sticky bra.

Simple and cute

As with most Reformation pieces, this runs small. Sleeves would NOT stay up so had to wear with a jacket. On the shorter side and material is thin cotton.

so so so cute -- but size up!

I was worried this would be too big as I am usually a size two but I ordered the size four because it was the only one in stock and it was actually perfect. I own a reformation top in a very similar bodice cut (one they do a lot!) in size two and I struggle with my boobs coming out of that top, although it looks like it fits perfectly / doesn't look like they're going to come out. For that reason, I would recommend sizing up if you have bigger boobs — or even, just not very small ones. My boobs are on the smaller side (I'm a 30E, which is a very small band size) and this made them look great, while the larger size kept them from falling out. You can't really wear this dress with a bra, though, as you will be able to see the edge of the cups. (Unless that's your vibe, which is great.) On a more fun note, this dress was so fun to wear. I found it easy to dress up or down, and it made me feel super feminine and chic. It was also super comfortable. It's also insanely flattering. Out of everything I tried this month, this is the thing I'll have the hardest time saying goodbye to. I've worn it a lot, and would definitely buy it if I could afford it!

a stunner

Overall a stunner, made me feel romantic and beautiful, highlighting the assets in the best way possible, chest lifted, made my waist look slimmer, hides my trouble areas: arms and shoulders (I'm always self-conscious). I used fashion tape to keep the sleeves up. It worked out nicely while I was strolling down in 100F humid summer weather in Madrid. I think I'll buy this dress.

LOVE this dress!

This dress was a hit. Very comfortable and not too short. I was not sure how a reformation dress would work for me, as I believed my sizing seemed somewhat outside their demographic. I was very pleasantly surprised and would highly recommend this dress! Light material so not too hot in the summer months either.

Lovely little dress

Loved this dress for a cocktail party-type event. I’ve found that I need a 4 in Reformation dresses when I usually wear a 0 or 2 in other brands. It was slightly loose in the shoulders, but no big issue.

A little roomy in the busy area. Would recommend wearing a strapless bra and maybe using some bra tape since bra strap will show.

Cute Dress but Sleeves are Impractical

The dress is flattering and cute print. However there is no way the sleeves will stay up without the assistance of lots of fashion tape.
