Cute top!

I really liked this top, though it did run a bit small. I'm not at all chesty, and it was pretty tight around my bust. When I first put it on, I was worried the shoulders would fall down, but they stayed in place really nicely!

Fun top loved it

Didn't need a bra (small chested) and the shirt kinda lifted perfectly. Needed fashion tape on shoulder to keep it up but wore to 2 different events and loved it- would rent again.

Obsessed!

Ref is always super flattering and this top does not disappoint! I usually find this brand to run a bit small but the sizing on this top is spot on. There is a side zipper but the bodice has a bit of stretch in the back.

Such a cute top but…

Such a cute top but you need to wear a strapless bra. It’s just too hard to wear a regular bra with how way the sleeves sit.

Cute little thing

Paired well with jeans. There were some distracting bits: very cropped even with high-waisted pants, chest super tight, and shoulders wide and loose--kept having to readjust here and there. Looked great, though!

Cute top

as with everything Reformation, I find this to run a little small but it was stretchy in the bodice so didn't matter too much. I have a very small bust so this worked well for me but not sure if it would be great on someone with a larger bust. really cute top!

Flattering and fun

Such a great top. wore it to a bluegrass show on NYE. You'll need double-sided fashion tape to keep the shoulders up but the tape worked great and stayed in place all night. The size was perfect.

Beautiful!

This was a beautiful top! It’s a little tight in the chest for a large busy, and a bit low cut, but wearable! I got a lot of compliments, especially on the shoulders, which are a little poofier than the photos.

Very pretty but a little tight

I wish there was a little more room in the bust area - I'm a B cup and my chest was pretty squished, so maybe it's just not the right shape for me. The cut & pattern were super pretty though.

Wore this out to dinner one night. Super cute but if you're any bigger than a B cup I could see it not fitting. The cups of the shirt are really small

Cute crop, tad small

The shirt is a casual cute top, slightly too tight in the chest if you have a bigger cup size, but still appropriate. Typical for reformation tops, to go braless if you can. Perfect in the waist/arms.

Made for petites

This shirt is so cute but unfortunately did not fit well. I am usually a 4 or 6, I ordered 6 because I read that it ran small but I wish I got the 8. Though, I still don’t think it would’ve fit well - definitely made for those who are very petite with smaller boobs (I am small but I wouldn’t say “petite” and I have 34C). The seem in the chest area gave me major pancake boobs without a bra and still mild pancake boob with a bra and sat essentially on the center of my boobs instead of under them where it’s intended to fit. I probbbbably could’ve gotten away with wearing it out but I would’ve been pulling it up all night and it just wasn’t comfortable. TLDR: great if you’re very petite with small boobs

A little snug for the ladies with larger chests. I still make it work, but it's designed for a smaller bust.
