Love this medium!
I tried this on in store in a small and then ordered the medium online i loved it so much! i generally run a small/medium with retailer so i thought this was pretty true to size. i'm also longer through the torso so the medium is better for me to cover my stomach when tied.  it is on the thinner side but not see through. perfect for layering and for a mild california winter. can't wait for it to come!
