I ordered this jacket because it seemed to have all the features I was looking for at a decent price, and I didn't really care that it was made for boys (even though I'm a woman). I ordered an XL, and I am 5'2", 125 pounds, and my shoulder width is 17" across (if that helps with trying to figure out size). The jacket fits perfectly, and is even a little bit roomy (which is good because I can wear a sweater underneath. The quality of the craftsmanship of this jacket is excellent, and its super warm and comfy. The colour is a bit of a deeper orange than on the picture (think "pumpkin" coloured), which is actually good because it will make me more visible on the slopes. In all, I'm very happy with this purchase.
