I got a 2XL and it is a little small.
Runs small, size up at least one, two if you like a looser fit like I do. Nice soft fabric and a good tailored design. I exchanged my large for a 2XL and they were great about letting me do it after Christmas and without a receipt...responding to my email within a day. I've never seen a cuter t-shirt with my Lucky -dawg's face on it! They're hard to find so I'm very happy to have such a nice shirt, I'm going to have his name added to it somehow.
