Adult (or teen) winter coat size xxs by Nau. This coat is very very warm (I wore it in Vermont Winters), and it's about knee length on my 5'4" frame. Although the size is xxs, I think it fits more like an xs. The hood is really cool because it is designed not to be blown off in the wind and it has some nice details like the inside pocket and headphone elastic to keep organized on winter outings. Originally, this jacket is over $300.
