I am 5'7, 119lb and my bra size is 34A. My waist is 26'. Size S fits good! the length of the jacket is a bit short for me, though, but because I wear it with jeans, it works for me. Well, maybe I'll try it with office pants later too :) The jacket looks like on the picture. Material is very soft, light, and hard to wrinkle. Shoulders are slightly padded, which is nice (in the same time you don't feel like a King-Kong or Halk.) Don't expect a very good quality of classic jacket/suit from this jacket - it doesn't have any additional linings. Basically its cost reflects its quality. So take it easy..
