Took a chance with less known brand and loved it! I'm 35-29-39, AU 10, and bought the jacket in XL which fits perfectly over a tank top/cami. I love the unique cut and the slimming effect. (I own another white jacket that I rarely wore because I look huge in it). I don't think this jacket is meant to be worn with long sleeve shirts/blouses though. The color is white, not offwhite like in the photo. The material is not so heavy, perfect for Spring/Summer.
