Either at home or at a gig?

I think I have picked up a guitar occasionally on a hot day when wandering around the house sans top, and yeuch!!! Feels horrible. I'm surprised that anyone wants to play like that, even if it's really hot, in which case the guitar probably sticks to your skin.
Helps if you have a Phil Collen body I guess. And there's something primal about it if that's your thing. Its not a look I like to be honest. Needless to say, my bod is not one to show off.
Anyone done it, or have an opinion on that sort of thing?
And a bonus point for the first person to recognise the middle guitarist. A band I was obsessed with back in the early 80s!

Those above are not acceptable. Collen always looks too-well-oiled in an uncanny valley way
Trousers.... that's a different question.

I'm far too hairy. People would wonder why I was wearing a fur coat
But with my chaps, boots and muir cap on ....for protocol reasons....
*An Official Foo-Approved guitarist since Sept 2023.
And I think the bloke in the middle is Mark Farner.
Always gets the ladies going... Often for the nearest exit
I did once buy some kind of compression T-Shirt when I had to wear a suit and thought it wasn't going to fit. It was very uncomfortable and seemed to make my torso an even worse shape than it was already.
