Westwood won't design Middleton's wedding dress

London: Fashion mogul Vivienne Westwood insists that she had turn down a request to design the wedding dress for Prince William's bride as she thinks Kate Middleton's style is too outdated.

Prince William is set to marry Middleton in April and gossip is rife over who will be designing the outfit for the big day, reports a website.

But Westwood is adamant it won't be her because she's not impressed with the 29 year old's fashion sense.

"I would have loved to have dressed Kate Middleton but I have to wait until she kind of catches up a bit somewhere with style," she said.

"Sorry, I'm not going to say any more, that's it. When people ask me where she's going to get the dress from - she's definitely not going to get it from me," she added.
