This t-shirt is soo stinkin cute!! I’m a medium in just about everything and this was my first pulse “t-shirt” purchase so I decided to get this in a large because I never know about t-shirts. They can be a little too snug or too big and then could look sloppy. But I have to say, I definitely could’ve gotten away with a medium. It’s comfortable in a large but I’ll definitely know for further purchases in pulse t-shirts that a medium will be just fine for me.
