I debated buying this, so glad i did. tts. i'm 5'5" 115 and 32c. i got size 2, and it worked but i could have done a 0 (which is my usual size). i was afraid to order it too small because i needed it right away! this dress is gorgeous! i got the pink color way and it is more vibrant in person. the beading is beautiful, it's incredibly soft and flowy! this dress is probably my favorite dress ever! if you're on the fence, order it!
