This top is honestly so beautiful, I wear a size L & that's what I ordered and it fit amazing. I am on the smaller chest area side I just put the pushup nipple covers and it looks good. I ordered one for my sister she wears a M but that size was sold out so I got her a L & it fit big but she decided to keep it and just make it work cause she loved the top too much & couldn't wait until its restocked.
