If your shirt is too tight, you'll look like a fag trying to flash his body through his clothes wherever he goes. Men don't do that. That's an effeminate/homosexual trait. Your shirt should fit at a few places like the shoulders, wrist and hem (long enough to be able to tuck it), but be reasonably loose at others, like the chest, waist, back, arms, to allow good airflow and movement.
