Shirtless opportunities

So rush week is going on now for frats at my school. I was thinking about checking out a few and see if I can practice being confident going shirtless there since it’s pretty common with frats. The one I went to today, I asked the president over text if going shirtless was allowed. He said yes within reason. When I asked again he said “I wouldn’t show up shirtless to the rush events”. But then when I clarified that I meant if I could take it off like in the middle of something he said “Ahh ok, I’d just say read the room and if it seems appropriate you do you. So I went to their house tours and taco social today hoping to have an opportunity to go shirtless with the guys. But the main event was outside and it was rather a bit cold to go shirtless and nobody was doing so, so I decided not to even tho I wanted to.
But I also reached out to this other frat who also seemed pretty casual with shirtlessness judging from their insta page. So I asked one of their officers if it was allowed at their place and he just said “That’s kind of a weird question. It depends on the situation I guess? We don’t have any rules against it.” So I’m thinking of going to their dodgeball rush event in 2 days. Being a sporty event maybe that would be a more appropriate opportunity to go shirtless. I mean it’ll still be a bit cloudy. But I’m hoping to get hot/sweaty enough that I’d have a reason to take my shirt off, and possible influence other guys to do the same.

Any thoughts, bros?
