1/2 size large (100% of responses)
I am 5'2", 120 lbs, 34C. I ordered this dress in a size 4 and had to get it altered. It was a bit long on me so I had it hemmed, but now I'm realizing I'd actually like to get the shoulder's taken up to reduce some of the boxiness in the chest. Probably wouldn't have bought in the first place if I knew I'd have to alter it several tims, but that said, it's absolutely adorable now and I've gotten a ton of compliments on it. Very comfortable and quality material.
I got this in us size 2 and it's just ok. I can't see myself wearing it more than once so it's going back. If I move my arms at all my bra strap shows at the back. And it's pretty shapeless. Kind of reminds me of a night gown. I'm 5'6 120 lbs, 26" waist, 36" hips, 34b
