something not for facebook

[prgrmr]

Victoria's Secret was running a commercial this weekend about their semi-annual sale and that everyone's favorite bras and panties could be found there. I immediately wondered if my former girlfriend would be there, as whatever bra and panties she happens to be wearing at the time are my favorites.

And this, of course, begs that now century old question: why is "bra" singular if "panties" are plural?
