Formula One world champion Lewis Hamilton has missed out on seeing Novak Djokovic defeat Roger Federer in the Wimbledon final after being barred from the Royal Box over a disastrous fashion failure.

Hamilton was due to join celebrities including actors Benedict Cumberbatch, Bradley Cooper and Hugh Grant in the exclusive enclosure at the All England Club on Sunday.

But the British racing driver and former world champ was unable to watch Djokovic’s four-set victory because he wasn’t wearing a jacket and tie. And the shirt, well, if you can’t say anything nice …

With the match at 4-3 in the fourth set, a Wimbledon spokesman responded to reports that Hamilton had been turned away by saying: “He did come but he has gone. We are not commenting further.”

Earlier on Sunday, Hamilton had posted a picture on Instagram showing his Royal Box invitation package.

In the photo, Hamilton did not appear to have a tie or jacket on.

A Wimbledon spokesman later added: “If he was not adequately dressed you could infer that he would not have been let in, but we do not comment on our guests.

“If he came without a jacket, tie or shoes he would have had two choices – not staying or going to get some extra stuff.”
