This coat is very warm with fur lining the inside of the arms. It's a free size, but I think it's suitable for S-M sizes, or those with a slender upper body who wear L. The lower body has room. It has pockets on the sides. You'll be warm enough even with just a t-shirt or shirt underneath. The fur is a pale color, like gray and greige, and is only on the neck and sleeves, so it can be worn in a clean casual style. Length: Approximately 81cm Width at chest: Approximately 45cm Because of the inner fur, it will actually be a bit narrower. 90% wool
