This dress is gorgeous and I received tons of compliments. The quality is very good. I was very surprised how expensive this dress feels. It is an actual true to size or slightly smaller feel. I purchased a M which is my normal size and it just fit with no extra room. I am not sure if a size up may have been better but it does give a bit with wear. I found it slightly tight in my arms but i have bigger arms for sure. I am a 38C cup bra, 4-6 waist and 5’7 in height. The dress fit like a glove but if you want wiggle room maybe size up. I would keep this size as the look was very flattering. Hope this helps and if so drop me a like?
