I am 144,5'4 ,34 D, and i have a small butt.I usually wear a medium. I ordered a large. The large fits perfectly, although the most layering I can do is maybe a thermal top. The jacket is warm ,waterproof and windproof. I feel that a thermal is all I need under it. But if you prefer to layer more, you should order 2 sizes up. This is a nice shell overall and not bulky. I am very happy with my purchase.
