That sounds OK. What I DON'T really like is when guys try to look all hot at the gym by wearing tank tops and tight shorts and stuff like that. I also hate it when they are like sagging or wearing things that are NOT for working out.
If a guy is hot, he's pretty much going to look hot no matter what he wears, and same if he's not, so yeah all of that sounds ok.
I go to the gym to work out, not to see guys, lol. That doesn't mean I won't stop to appreciate someone's looks, and body if they take care of it. Just don't over do it and look like your purposely trying to look sexy. You should wear your basketball shorts..with a snug shirt..not loose.
