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 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?
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.
Some guys don't seem to appreciate a loose tie because it's sloppy. I think that's the point. I especially like a loose tie when the guy keeps his coat on. Which is better for you?
