These shirts run VERY small. I ordered men's L and XL, and there's no way that they would fit a large or extra-large man. Also, the fabric, 100% polyester, almost feels like plastic and has a slick texture. I've seen plenty of polyester shirts that are much softer, but this shirt is nothing like those.
If you're ordering shirts that run VERY small and are using them as painting smocks or something else, then these would be fine, but I don't know how I feel about having these next to my skin.
