Great shirt, dry cleaned just to keep the shirt's fashion pattern from fading, but if you're slim as a toothpick with no muscle mass, order a size up than you usually wear. I'm 5'6, 150 and physically fit but definitely not bulky. First I ordered my usual tote... I was like a stuffed sausage; had to return it for a large one and then the tailor shortened the length…. It's worth it, it's one of my favorite shirts.
