Duchess Catherine can't seem to please anyone in the fashion world.

First Matthew Williamson slammed the future queen - known at the time by her maiden name Kate Middleton - on her style, and now Vivienne Westwood is chastising the royal for not recycling her clothes.

"I don't have any advice for her, [although] I think it would be great if she wore the same clothes over and again, because that's very good for the environment and it would send out a very nice message. If you're going to all that trouble to get an outfit that suits you, then you should keep on wearing it. I mean you don't have to have a red outfit one day and then something almost the same in blue the next," the veteran designer said at London Fashion Week.

While it's humorous that Westwood - who herself puts out a new collection of clothes at least twice a year - called Duchess Catherine out for not recycling her clothes, Fashion Police correspondant Kelly Osbourne blasted her about re-wearing her clothes a couple years back!
