Kate's dress designer is still the best kept secret in Prince William's outfit has now been confirmed.

William will wear red to honour the Irish Guards regiment for his walk up the aisle. He will also be wearing his Garter sash and star, Royal Air Force 'wings' and Golden Jubilee medal.

William was expected to opt for his blue, RAF uniform but we think it's safe to say he will look ever the handsome prince, no matter which colour he goes for. Only four hours to wait until we see the wedding outfits!
