I tried this on yesterday in the store because i was drawn by the rich purple color and pretty print. i took my usual size 2 (5'2", 110 lbs) and while it fit well, it did leave too much room in the bust and around the shoulders/arms. i had the store order me a 2 petite, and am confident that this will help. the shape of the dress is a bit straighter than it appears in the picture and it didn't gather in the waist at all, but i still found it flattering. i'm sure i will get great use out of this
