Kate Middleton's 'modest' wedding dress

Britain's Kate Middleton's wedding dress will be "modest" according to fashion designer Bruce Oldfield.

Prince William's bride-to-be will cover up any bare flesh with sleeves and a veil on her April 29 wedding, claims Oldfield - who is rumoured to be designing the gown.

The legendary designer also revealed on US breakfast show Good Morning America that stunning Kate, 29, will have a second dress for the evening dinner and dance - hosted by her future father-in-law Prince Charles.

Asked if she would have two gowns on her wedding day, Oldfield replied "yes" but refused to give any further details on the style or whether he had been commissioned to create the wedding gown.

However he admitted that the dress - despite being modest - would draw a strong reaction when she arrives at the ceremony at Westminster Abbey on April 29.

Oldfield said: "Whatever happens, there's going to be a sharp intake of breath, 'Shhh - oh my God, what is she wearing' or, 'Oh, doesn't she look fabulous?'.

"I'm sure the dress is going to be modest in terms of coverage - it has to be. It will have sleeves, it has to have sleeves.

"You can't walk down Westminster Abbey in a strapless dress. It just wouldn't happen. It has to suit the grandeur of that aisle, it's enormous. I can predict she will wear a veil."

He added: "Whatever she wears, she is going to look great because she is gorgeous. She's slim, she's elegant, she is aware of herself. When you see her moving, she is not a shy, shrinking violet. But she is a normal, ordinary girl who happens to have bagged the big one."
