I like longer sleeves to prevent further sun damage without overheating with long sleeves. I usually have to buy Men's or Unisex Small to avoid the short short-sleeves of women's fitness wear. The Aggressor sleeves go to my elbows, and don't bag like men's/unisex shirts. It runs long and is semi-fitted. I'm 5'4", 120 lbs. I first ordered the medium and it was pretty loose and fell 2-3" down my legs. I ordered an XS and S. The XS is body-hugging, so I'm sticking with the Small, which is a little looser and the torso length is good.
