Kate Middleton shouldn't be the next Princess Diana

Britain's Kate Middleton doesn't need to become "the next Princess Diana".

Irish fashion designer Paul Costelloe believes while the brunette beauty - who is marrying Prince William on April 29 - should be praised for her style, he hopes she isn't turned into a carbon copy of the late princess.

He explained: "She's a lovely girl, she dresses well and she's got a nice figure. But I just don't think we should be sending her into these fashion areas where she doesn't want to be.

"She shops in Peter Jones in Sloane Square, she bought some of my clothes probably during the sale, which is great. You know, we don't need another Princess Diana, as much as I had great pleasure in dressing her."

Meanwhile, fellow designer John Rocha praised "gorgeous" Kate for looking stylish, while being a "normal person".

He told BBC News: "I think she's a gorgeous lady. It's great that she's been able to get the whole country excited. We're proud of her and the whole occasion.

"I think she's very stylish and what I like about her is she's a normal person and I think that's very important to bring the whole royal family into the new century."
