I’m 5’6, 115 lbs and got an XS. It fits perfectly with extra room for sweaters, but you don’t need sweaters as the coat is pretty warm. This is not for people looking for a snug/fitted coat.

I am 5'3'', 108#. I bought a XS and it fits perfectly. the shoulder, sleeve, the length of the coat is a good fit. I order a brown color one, while it is very warm, and feels good have it on, I look like I am in a whisky barrel. The cutting is not flattering. However, it is a practical piece of garment. There is room to have a heavy sweater underneath if you are going to play in snow.

The arm length is a little short but overall everything is great. It kept me really warm in 10 degree weather. I love the color glazed pecan. I normally wear large, this fit really well and I’m big everywhere.
