I am very petite and I got a small. I have a size B chest and the top part could have been a little smaller, but it fit wonderfully. It is extremely cute and I can't wait to wear it! I seriously recommend this dress. My only concern was how long it took to get to me.
I ordered this dress in a small and I really love it but I just can't get the zipper up in the back! I definitely should have ordered a medium, so I'll probably be returning it, but it's completely my fault and no fault of whoever made it! It kinda is a weird sticking on the chest and my boobs kinda make the buttons pop but I like it!
I ordered a small and received a medium. Absolutely love the way it looks on! Definitely a vintage look, I did have to trim some of the unfinished seem lines and the top bottom broke off as soon as I put it on. It's a fragile made dress but worth it for the cheap price!
