I bought a XXLT FD hoody last year, needless to say I sold it to my brother who is 6'7-ish. I try to keep my stuff around 37.5 inches long, as I am 6'4. That kid looks like a goon though.
This is my outerwear this year. I have never gone close to this tall and i kinda feel like a jackass but who gives a fuck. Ill wear a sweatshirt most of the time anyway.
