I am 5'. I tried on the Northface Denali in the girls, boys, and ladies departments of Macy's a few weeks ago. The ladies XS was considerably larger across the body and shoulders than the girls L, but it was a bit shorter. The girls XL was too big. The boys jacket was cut way too big for me in the body in the large and medium, and the small was too small.
The girls large was the best fit for me. I bought one online because it was cheaper. Although I would have preferred the shorter length of the ladies XS, it was just too big.
