I purchased a Large for my wife and a Medium for our 13 year-old daughter to take to Costa Rica this June. My wife is a slim 5' 8" and usually has a problem with sleeves being too short. The large is a perfect fit length wise and loose enough for layering without looking too large. Daughter is a slim 5' 4" and again, the Medium fits her perfectly. Hope this helps.
