I don't see what the problem is with men wearing pink. It's a complimentary color with say, navy, black, gray, and khaki. Did I also mention that, at least with my experiences and observations, girls like guys wearing pink?
Oh, and the "Real Men Wear Pink" came from our all guys school, and it was part of a campaign for the Susan B. Koman Breast Cancer organization. But the slogan also suggests that men that wear pink are confident, but at the same time caring.
