I am 5' 1". I weigh 160 pounds. My bust is 42" (36 DD). My waist is 37". I have a short torso. I am usually between a size medium and large (8-10). About 95% of the time, I get a size medium from ByEgreis. Unless Egi advises to size up due to stretch and bust size. In this case, I ordered this jacket in a size large. Its a perfect fit unzippered. However, if I zipper it up, its a lil too snug for my liking. If I would've gotten a size XL, the sleeves would've been too long for me though. I love the color. Looks great with my sage colored Kai joggers. The jacket is stylish and chic. The material is so soft. There is no stretch to the jacket. It is short/cropped. So if you don't want it too short, size up.
