I put my Oregon Ducks tee-shirt on today for casual friday (football games held at Autzen on Saturday's usually result in a free casual jean's day at my job on the friday before). This shirt was just bought last year and it's a men's 2x. Today, I just had to go get a new shirt since I was swimming in this 2x. I bought a men's large at jcpenny. And it's not exactly tight on me. Well, maybe a little (but not noticable) around the waist but it totally fits and I am so estatic.
