I used to stay away from pink until about 10 years ago. Back then I switched to working in an office environment and noticed that pink was an acceptable color (used to always stay in the blues/tans/white). Now I own alot of colors that I never did before (pink, lavender, pastels), and I started wearing these before I came out to the wife. The only time I see guys sticking to plain white is when I'm working in one of the government buildings, then it's all black or dark blue suits, white shirt and then maybe a wild tie or two (most ties are just the power colors).
Kind of reminds me of the old days of IBM that i've heard of----black suit, white shirt, black tie. Or if you're a movie buff----Men In Black.
I even think to myself when I see those guys in their suits at work that they're nothing but of posers, sucking up. Personally, I'll just stick to some nice slacks, dress shirt of my color choosing (including my pink one), and keep a sport jacket on hand in case I have a meeting with a govie that day.
