I'm 6'1" tall 190 lb male. I usually wear a medium size button down, short sleeve shirt. Description says boxy fit but I find it to be rather slim fit through the torso with sleeves being a little long. I bought this shirt in a large, which is a size up from my normal size of medium. I'm kind of a skinny dude but I find the large to be a lil tight in the torso. I've only washed the shirt in cold water and been careful to hang dry as it's 100% cotton. The aqua color looks great and I really like the shirt! If you are trying to decide between sizes you should DEFINITELY go with the larger size! Great shirt and great colors!
