“Beautiful shirt, but buy a size up”

“I bought this shirt in the earth color which is rich and lovely. It is beautiful, high quality in appearance. Sleeves are good long length, and it fits long on the torso. Re size, Patagonia small top is a perfect fit on me. Fortunately, I read Ski Bum's review and ordered both a small and a medium. The medium fits me like a gently snug second skin. If your skin skin fits as sleek as this shirt, you could wear it as an outer layer. If not you'll need a Spanx or second layer. It is sized and intended as a base underwear layer, though still one size small for that. I was going to return it, then tried the medium on again with a black vest and running tights. It looks great that way. It also looks great under the Eider Maelle Fleece jacket and does not grab or stick to the fleece. So I will wear it as a base layer until or if I ever have not an ounce extra on my torso.”
