Chalkstripes and Pinstripes

Except for the light gray, this is my top favorite. The stripes literally follow a man's suited body, enhancing every shape, bend, bulge and curve.

Rolled-up Sleeves

Why is this sexy? What's your take? The powerful, beefy forearms and the insinuation of strength?

Dressing UP

Almost as erotic to me as the suit strip... a man putting on a suit or tuxedo doesn't even need to be especially hot to look hot doing it! This is a random sequence stolen from some Flickr member on his wedding day...

The Vest

The three piece suit... very hot when it's just a two piece, too. But unlike the simple pant and jacket, which is basically not a suit anymore without the jacket, with the 3-piece, you are still pretty much wearing a "suit" if you're wearing a matching vest and pants. Isn't it great how it enhances shoulders and slims just about anyone up?

Suit Strip

At some point Playgirl magazine decided to cover up their models' private parts, to totally disappointing effect. Back then, this spread titled "L.A. Law" came out.
