Fashion icon Dame Vivienne Westwood has called on the Duchess of Cambridge to stop buying so many different outfits and instead make more of an effort to be environmentally friendly by re-wearing what she has.
Before her London Fashion Week showcase at the Saatchi Gallery, Dame Vivienne said that when Kate goes to so much effort to find an outfit that looks good, she should wear it more often, and in doing so set a good example.
The designer, who believes in quality over quantity, disapproves of Kate's expansive wardrobe.
She said: "I don't have any advice to her, except 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."
After his showcase in Covent Garden's Royal Opera House, designer Matthew Williamson expressed his opposition to Westwood's comments on Kate, who has been pictured wearing his designs.
He said: "She has a lot to do doesn't she? So she needs a good wardrobe. So, no, I disagree." When asked if a girl can ever have too many clothes, Williamson said: "Of course not."
The Westwood and Williamson shows were two of the most eagerly anticipated events on day three of the fashion extravaganza.
Westwood, dressed in her usual wacky style with an image of herself and the slogan 'I am Julian Assange' emblazoned on her T-shirt, said Sunday's Red Label collection also carried the theme of quality over quantity - but that does not mean less glamour.
"It's for anybody that wants to dress up quite wonderfully glamorous," she said.
