Wear an old beat-up t-shirt like everyone else.
If you're less than in perfect condition, you can bet every guy in there is thinking "Look at that wuss thinking he's hot shit".
If you ARE in perfect condition, you can bet every guy in there is watching your every move. If you ever have to have your spotter step in/can't finish a set, they'll all be laughing to themselves.
Is
this your gym?
To reiterate what some have already said, tank tops / sleeveless tees are perfectly fine. On most days I'd do 2,3 sets of oly / big lifts, some isos, interval cardios, and get the hell out within 45 minutes or so. I'm not there to impress anyone; if others think of me as a tool, so be it.
Jon,
this Champion shirt works well. For some reason size selection on the site is a bit limited. Their C9 line, available at most Targets, is good as well. Many here have had good experiences with the brand.
