I wear pink neckties on occasion. Sometimes a pink shirt. Even pink socks, once in a while.
But I'd draw the line at (actually, somewhere before) a pink suit.
At least in my mind, that suit crosses the line which separates "clothing" from "costume." Hey, it's just my personal take on it. I realize that lots of men routinely wear things which I consider to be truly hideous, and sometimes clown-like.
But just to show that I'm sexist, I do think a pink suit can look good on a woman.
