I stopped asking H that question, whether it's severely wrinkled pants, a shirt with an old hotdog grease stain on it or pants that fall off his flat behind. He's the one who be getting stared at, not me!
Maybe you could just ask the same question back? And just keep asking questions? I think it's kind of rude of her to ask.
And I don't think we as wives should have to dress our H's - I mean, they should be old enough to dress themselves, iron their own shirts and pants, match their socks, etc. Jeesh! If my H wants to go out looking like that then I should let him! How else will he learn? Haha.
