Well, it’s not only that, a lot of people are wearing costumes, that may or may not cause them to sweat far more than their normal day. A friend of mine wore a costume that involved a dress shirt and a coat, and Sept isn’t really cold in GA. He used menthol to cover for his sweat though, so it wasn’t too bad with him. My last costume (several years ago, I dunno where all the stuff is and can’t afford to remake atm) involved dress shirt, a vest, and a heavy coat (trying to emulate this character) and it was hot as hell, especially in lines outside in the sun.

Even with baths and deodorant for some people in such situations it’s not really enough.

A lot of choices are made for us. People who think it’s down to only choices probably ignore all the luck and privileges they experienced. I could have been born in much worse circumstances than I was, and that would not have been due to any choice I made. Children dying in war zones made no choices to get there.
