The Internet frenzy is building over what royal bride-to-be Kate Middleton will wear on her wedding day, but at least Britain’s prime minister has settled on his outfit. After a public back and forth this week, David Cameron is expected to wear a morning coat, complete with tails, to Westminster Abbey.

The invitation to the April 29 wedding of Prince William and Kate gives men the option of uniforms, morning coats or lounge suits. Religious leaders are allowed to wear clerical outfits, and the groom is expected to wear his Royal Air Force uniform.

Downing Street officials said Monday that Cameron would wear a business suit to the royal wedding. An Associated Press article noted that the prime minister “has been reluctant to wear outfits that remind voters of his elite education.” Cameron was photographed in white tie and tails when he was a member of an exclusive dining club at Oxford University.

Britain’s Daily Telegraph reports today that criticism following the choice of suit led advisers to rethink their decision.

“Insiders claim Mr Cameron was not consulted about what he would be wearing and that his advisers made the decision for him – a decision they have now come to regret.

“A source close to Mr Cameron said: ‘Of course he’s got to wear tails. He knows that. He’s the Prime Minister, it’s the Royal family, there will be foreign dignitaries present and it is only proper that he dresses for the importance of the occasion.’ ”

Cameron’s wife, Samantha, whose style is widely watched in Britain, is reportedly considering her own break with tradition: not wearing a hat.
