Funny, but I'm 47 and I grew up in the 80s in a farm community in rural Alabama. Even thought we were a rural farm community, we still had TV and Miami Vice still made pink a very popular color for men. It may look silly and dated now, but a pink t shirt under a white linen jacket with the sleeves rolled up, Docksiders (no socks), a pair of Ray Bans, and a couple days growth of beard was the epitome of cool at that time. I also had a couple of pink dress shirts.
What's more, my mother loves to tell the story of how, when she met my dad at a party in 1956, he was wearing a pink shirt.
Somebody else said this, but I don't think I've ever met a man who couldn't tell the difference between a man and a woman when looking at them from behind. Men and women tend to have differently shaped bodies.
