Maybe you. I sweat a lot and if I'm wearing polyester, I stink so much even I can't bear it. I would need at least three suits a week and they would need to be cleaned each week. Tossing cheap cotton clothes into washer every week is much easier and I always wear zip-up hoodies when it's cold, so it's easier to thermoregulate.

Maybe it doesn't work if you sweat a lot, but undershirt and a shirt should absorb most of it. Or you actually get three suits and dry wash them each week if it's important.
