Vivienne Westwood urges Kate Middleton to recycle clothes

It might seem strange for a fashion designer to tell someone to buy less clothing, but that's exactly what Vivienne Westwood is urging the Duchess of Cambridge to do.

Environmental campaigner Westwood said the Duchess should recycle clothing:

"I think it would be great if she wore the same clothes over and again. That’s very good for the environment and would send a nice message."

"If you're going to all that trouble to get an outfit that suits you, then you should keep on wearing it."

"You don’t have to have a red outfit one day then something almost the same in blue the next."

Kate has indeed been spotted wearing outfits on more than one occasion in the past - including a blue tweed M Missoni coat, an Emilia Wickstead pink dress, and nude court shoes from LK Bennett, as well as lending her mum a dress from Reiss (see gallery above).

Some have called it a fashion faux pas for someone in the public eye to be caught in the same outfit twice at an event, but designer Matthew Williamson was quick to jump to Kate's defense:

"She has a lot to do so needs a good wardrobe."

Should celebrities and the Royal family set a good example by recycling outfits more often?
