Brought two, Medium fits great looks fitted and stylish yet give a little room for a long warm T shirt underneath if needed. I am 5.8" at 130 pounds with strong arms and shoulders with a small middle and hips so I find it hard to find things my size but these fit and looks great. Wash well and very comfortable and warm too. You can dress up with skirts and ware casual with jeans or even add it to your sports ware in the colder months they are great. The collar also looks great zipped up to the top and folded over. Wish they did a dark gray.
