I currently measure 37-28-37 (34C/32D) and I ordered a large. At this size it leaves room for a sweater underneath. The cuffs reach to my knuckles, which I prefer in colder weather. It's a sweatshirt in the style of a jacket, not a proper jacket, so it's one layer of fabric, no liner. The advantage to that is it will be easy to tailor if you need to. The disadvantage is, well, it's not a jacket. If you need something warmer than a basic hoodie, order up a size so you can layer, or pass on this aSee full review
