I'm a six foot six man myself. Yeah dude,  we're fucked as far as larger sizes go. Once you get to large,  they don't get any longer,  just wider. Then it seems like most large shirts are too wide as well,  and medium is WAYYY too short. I've been buying clothes off the Internet now at sites that promote M tall and L tall clothing. Sure it costs more,  but it's worth it not to look like you're wearing a tarp.  Always stay away from stores that call themselves big and tall or whatever the fuck. They should just big called lard sized stores.
