“Perfect cool weather layer”

“I'm a pretty small person (I usually buy 32C bras if that helps), and not big in the chest area. The medium fits me perfectly - the shirt is still "fitted" but isn't clinging to my armpits or anything. It's -very- confortable all around - the fabric and the cut, and also very flattering because it is so nicely shaped, but not clingy. I'd say the small is only for someone -really- tiny up top in both frame, and chest. I say it's a cool weather layer because it's long sleeved. I wouldn't call the fabric super thin, but is pleasantly light, and could easily work in spring and fall as well.”
