I initially bought the red and blue sweater in a medium. i usually wear a large and the medium fits perfectly and is still a bit baggy. i'm tall (5'9") and so i love the length of the sleeves when they are unrolled. it's a very versatile piece. with sleeves rolled down you can fold the collar so the red is out of sight and just have a navy blue sweater. either look is nice. i loved it so much i bought the black and brown version. also, the fabric doesn't feel thick but it is very insulating and
