I'm 5'5 medium build. I wear a medium (8/10) in most clothing. I am bustier(36DD), and button up anything isn't usually my first choice, but this worked! I purchased this in a Medium and it fits like it was tailored for me. I received soooo many compliments on it and wished they had more colors. The dress looks structured but has stretch to it. The skirt portion bellows out like dresses that just stand the test of time. I hope they remake this every year!
