Would you wear just your underwear under overalls when doing a task like this?

In My Humble Opinion

If you were doing a task like in this video: House Of Kolor - How To Paint A Car - John Kosmoski - YouTube would you wear only your underwear under your overalls?

Personally, I would and have done.

For anyone curious, it’s a video of a dude painting a car in a car paint shop while wearing full-body overalls (like a paper suit), hood, mask, etc.

Nothing skeevy. Nothing note-worthy, either.

In that outfit, I’d probably be dressed underneath. For denim overalls like my dad used to wear, probably just a tshirt.
