Looking good, sir! Prince William has a new, sleeker look.
A royal source tells PEOPLE, “He has seemed to have become sharper since he got married, such as wearing a handkerchief in his top pocket. Some have inferred that it is his wife’s influence.”
Indeed, since he and Kate married 18 months ago, William has invested in new suits, says the source, with some up-and-coming Savile Row tailors replacing some of the more dated styles he’d favored before.
The source says that the fit on his Richard James suit, for example, “is much more modern than the suits he had when he was younger.”
Early in October, William wore a suit with neat, trim lapels by Spencer Hart – Diddy is a recent fan – to meet the England soccer team, while the following day, at a funeral for his ex-nanny Olga Powell, the prince wore an outfit by Richard James, who has dressed Tom Cruise, Usher and Daniel Craig.
