Bought this because I need some long sleeve shirts for winter. I got XS, I'm 5'6, approx 120lbs, measurements 33-27-34.
~Fabric: It is a soft, athletic fabric. VERY thin and stretchy. It would be good for exercising outside, but won't add much warmth compared to a 100% cotton top.
~Shape/size: Size seems good, maybe slightly baggy along the bottom. It is nice and long, which I need because I have a long torso.
I probably wouldn't buy more of these because I need something warmer, but not a bad top for under 15 dollars.
