I know you've heard it before, but this dress is so much more beautiful in person! i'm petite, usually size 4 but busty, so i tried the 4 and the 6 in the store. the 4 fit perfectly except it was a bit snug at the bust so the the slit pulled open, revealing a bit more cleavage than i wanted. the 6 fit perfectly through the bust, and although it was a bit loose through the body, the cut was still very flattering. i also tried the 6p, which fit but i preferred the longer length of the regular 6.
