I'm 5'5'' and 140 lbs. the medium size is perfect. The light shoulders pads (which are removeable) and the flare of how it hangs in front gives it a very nice dressy look for sleeveless dresses . Really like the 3/4 sleeve PLUS it hides ( most importantly ) the upper arms which are not as firm as when I was younger or just when your arms get chilly at night. The fabric works great with similar fabric.It hangs and flows perfectly.
