Wear what you like. Just bear in mind that anything white or any other light colour will, invariably get dirtier quicker (I'm thinking of a certain *not vintage* AG2R jersey I have which turns out to be a muck magnet). Also, as I found out with another jersey one time, the colours of the real thing can be much brighter than in the picture on the internet. A bit startling at first, but hey, if it helps get you seen on the road, who cares?
I only really know about jerseys as I refuse to wear shorts owing to the fact that I doubt the world is really ready to see me in them, let alone a one piece just yet.
