The shirt is great quality, but its sized like 1980. Definitely not slim fit, very loose. Except for the neck. I purchased the medium and I have a 15 neck. Unwashed, my head barely fit through the neck and it fit tight. I had flashbacks to the day of my birth, it was so tight on my head. Once I got my head through, I felt like I was being manhandled by the Boston Strangler! Good luck taking it off.... took a twenty mule team and I had to tie myself to a 100 year old oak tree. Breech birth city. Needless to say my girlfriend now owns the shirt!
