I wear size 6 but this dress didn't fit me. If you don't have a large bust i suggest to buy a size down. I have to admit that the dress is beautiful and the fabric is great quality but sadly i won't be able to use it because is too big for me. And I am not slim. I'm 5'2 hispano girl, wide hips, big butt, 133 pounds. and size 6 is too loose in the bust. Because the dress is so pretty and elaborated i wouldn't dare to modify it.
