I'm 5'5" 120 lbs and bought this in size medium because i have long arms and was afraid that the cashmere would shrink even if i hand-wash and dry flat (because let's be honest--i doubt i'll ever send it to the dry cleaner). it's loose through the body and arms, but the sleeves are the perfect length. the term "bell sleeve" is no exaggeration. the sleeves are billowy and voluminous and i can see them getting in the way while washing my hands or doing dishes. i guess i will have to reserve this s
