Maria Katowrote a review of The North Face Arctic Parka - Women's on April 2, 2011
I bought this parka for my wife in a medium. She normally wears a medium 8-10 in everything. She weights about 135 lbs and is 5'- 3" tall. She definitely never wears a size large. I exchanged the medium for a large, and the parka appears well made and was a good buy. However, the arm holes at the shoulder are still a little tight for her. Exchanging for the large was the right choice and now she can wear a fleece vest and a sweater underneath. I recommend a large in this parks if you normally wear a medium.
