Yeah. I'm trying to figure out why we say a phrase like " I'm in my boxers" or "she was wearing her bra and panties". Its a dumb question, but just something I can't seem to get out of my head now.
So I was reading a novel and it described a girl in her bra and panties.
It got me thinking why we say panties and boxers even though there is only a singular article being worn.
Why is that?
