The photos and description are accurate. I am a US size 10 (M or L) and 5'2 tall, I have send my measurements to the vendor and was told 3XL would fit well, but I wanted a very oversized look so I ordered 7XL. It fit as I expected. The coat is fluffy and soft, and light. The quality of the stitching and hardware/haberdashery is good so far. It's currently - 7 in Toronto and when I wore it over a t-shirt and lounge pants to walk the dog I felt hot, so I think with a sweater it might just be warm enough for - 30, it is wind resistant. Highly recommend.
Very cozy, get your normal size.
