Returning from Montreal several years ago after the Grand Prix I was in the airport at the same time as the Ferrari F1 team. They were wearing gray trousers (brown shoes that more or less matched their leather carryalls), blue blazers and white shirts - double cuffs with no links. I think they had them folded up over the blazer sleeve - ie the double came up the outside of the sleeve, covering the sleeve buttons. I say "I think" because I recall seeing a lot of white, but it wasn't covering their hands. They could get away with it. Not sure I could, or that I'd want to try.
