Fitness Room Flooring

I am a college student trying to get my abs. I have nice toned arms and my toned chest is starting to show, but I am just wondering something. I haven’t seen any dress codes posted for my college’s fitness room. Do you think a college would allow students to work-out shirtless in the fitness room. What about wearing a muscle? If I see another guy work out shirtless, do you think I should go for it?
