I wear affliction or ed hardy shirts only. I usually pair them with my pants that say “tap or bleed” or my rock revival jeans. I don’t actually compete in mma but I watch a lot of tv so Id probably be pretty bad ass. I wear way too much cologne , my couch is stained orange from my rub on tan, I drive a lifted truck even though I’m 5’2 , and gawk at every female that walks by. If there’s grass on the field … amirite boys ?
Honestly though for just t shirts - Gildan fits well , polo v necks have good stretch to them … in general it’s a pain in the ass finding clothes that fit that don’t scream “look at my muscles ! “ Douchery. It’s ok up to a point - but most people take it waaay too far
