I get a kick out of guys that workout and feel the need to wear tight cloths. If you are big it will show no matter what you wear. The man makes the man not his cloths. I would wear loose fitting comfortable cloths. Its a pain in the ass once you wear shirts in the 3x range. I am constanly having to stop and retuck my shirt in. I know allot of guys love to draw attention to them selves but I try to be subdued. I love baggy t-shirts and sweat shirts with those baggy cargo shorts. Just kind of a chillen outfit to kick back and be myself. I think its best to wear conservative cloths when outside the gym. When your not training try to just relax and forget about the gym.
