I am a true size 0 (5'3, 100 pounds) and the xs was SO tight. No stretch AT ALL. I was able to barely zip it up. Also has no bust darts, so if you've got a larger chest than an A it's gonna be hard to fit your boobs in the small area. Beautiful dress and great material, though. I'll have a hard time breathing but at least i'll look cute lol.

This was my prom dress and it was absolutely stunning, I posted a pic on my insta if you’d like to see it @alondrarodledz
