Simon Cowell, the snarky judge of the successful reality shows American Idol and POP Idol, is probably best known for exactly that -- his style of judging. His direct, no-nonsense, politically incorrect and brutally honest commentary has earned him nicknames such as Judge Dread and Mr. Nasty (probably naasty with a British accent).

Simon Cowell ranked 29th in the Forbes Top 100 Celebrities list, with his top attributes being "rude" and "mean." It's no wonder when he says to contestants things like, "If your lifeguard duties were as good as your singing, a lot of people would be drowning."

But as much as Simon Cowell is known for his snarky ways, he's also known for his manly monochromatic T-shirt collection, most notably the tight black Armani T-shirt, of which he owns 30, no less.

Jeans and T-shirt -- gotta love that, don't you? Who wouldn't wish to become rich and famous without ever worrying too much about what to wear? Wouldn't it be great if you knew that whenever and wherever you went, you could wear your jeans and black T-shirt? And this might be the exact appeal of Simon Cowell's "uniform"; it's plain, simple and any of us can do it. That's what I like about it. Cowell doesn't dress too fancy or patronizing (like fellow weasel Ryan Seacrest), so that when he says what he has to say, it's taken seriously.
