...and here a vest is worn underneath clothes.
It may be what Paul calls an undershirt. The most common variety, and only worn by older men, is a string vest. I had an example, but it was (quite rightly
) pointed out to me that the photo wasn't quite PG13. Sorry!
Anyway, a man's string vest is similar in
shape to the T-shirt Clark is wearing in the tattoo pics, but instead of being made of solid stretch cotton (standard T-shirt fabric) it's sort of webbed cotton - ie, like fishnet tights/pantyhose, it's full of holes.
And considered
very tacky these days.
Edit: Okay, found something. This string vest has larger holes than some, but still is a good illustration:
Though I now notice that string vests have become fashionable for women, and although sold as lingerie are intended to be worn as outerwear:
The women's ones do have larger holes than the men's:
I'm just getting old!
