Anything that's satin or silky and isn't navy, charcoal, or black. A woman can be wearing lime green or vivid orange and still be dressed nicely and professionally. For guys, an olive suit is about as far out as you can get and still be dressed professionally. It's sad.One of my friends in HS had the hottest little satin lime green minidress. As soon as I saw it I said to her "I have to wear that." Strange reaction, I guess, but it worked out. It was just so much more fun than anything I had ever seen in the mens' department. I think I looked cute.
