I wear a womens Small in other North Face Jackets..I would like to buy this jacket. I am 5 2" and 115 lbs. My arm length is 27" long(measured from neck to where I wear my shirts)

Kelly, take it from someone who often buys a children’s size XL to save a few bucks: the savings feel good. But the fit is almost never quite right. You’re petite enough that the sleeve length will probably be just fine. But The North Face, like other clothing manufacturers, uses a boxy cut for its girls’ clothing (basically, the same cut as the boys’ versions but in girly colors). For women’s clothing, the company’s designers take the time to make flattering tailored fits with princess seams and room for your curves and bust. So, ask yourself if it’s worth spending less money to get something you might not wear as often because the fit is awkward and slightly off. Spend a little more on the women’s version, and you might wear it every day because it’s both a practical fleece and a flattering one at the same time.

I just bought myself a Denali Thermal in Girls' XL and the arm length is perfect. I am also ~27" from neck to wrist. The body is a bit large though. I am 5'4" and 125 lbs and I have lots of room to wear several layers underneath the jacket, and the jacket covers down to the middle of my bottom.
