The wonder love sleeve tee is super soft and stretchy and slick. It is definitely not a shirt to keep you warm, but it is a nice layering piece and nice for those cooler days. My normal size large was a perfect fit. Not too loose and not too tight.
Love the color, love the feel. I throw this on over a tank or tshirt when I run and it keeps me warm on fall runs. It works great under a vest if I need an extra layer. I'm 5'3, 130 lbs, and wear a M. Another Senita victory!
