Personally, no. But then, I don't wear white anything because I could stain for England. Guys in white shorts... uh-uh, big no-no.

But in the pictures the models do look cute in white. So if you like white and ride in dry conditions, why not give it a try. Get a good friend to check the "visibility", though...

(Just rode behind a guy briefly yesterday, who was wearing very worn black shorts with a large circular thin spot like a bullseye right over his butt crack. My eyes still hurt. I very nearly tapped him on the shoulder and said something, but I just couldn't think of any conceivable way of saying that politely to a stranger.)
