British designer Bruce Oldfield – a favorite of Princess Diana’s – has been the rumored frontrunner to design Kate Middleton's wedding gown for months. And now, Oldfield is fueling speculation that Kate may change into a second dress for the evening reception, hosted by Prince Charles at Buckingham Palace.
"The wedding is going to be in the morning and then she will change in the evening for the ball," Oldfield told the Today show. "She will have a special dress in the evening, yes." Asked if that, too, would be white, Oldfield demurred: "I haven't the faintest idea."
The buzz surrounding this particular designer reached a fever pitch last month when mother and sister of the bride, Carole and Pippa Middleton, were spotted at his London shop.
Whether or not he's dressing the bride, the designer says he can be sure of certain elements of her look.
"It has to have sleeves," Oldfield told Good Morning America. "You can't walk down Westminster Abbey in a strapless dress." What else can onlookers expect during Kate's four-minute trip down the aisle? "I can predict she will wear a veil."
Of course, there are also those with differing dress opinions.
London society brides "don't seem to be changing from day to night," bridal designer Sassi Holford tells PEOPLE. Holford has her share of royal wedding experience as well, having designed Autumn Kelly's gown when she married Queen Elizabeth's eldest grandchild, Peter Phillips. "They want to wear the dress from the minute they start the day until late at night. For the evening, for instance, we would take the lace jacket off and put on a really sparkly belt or something that turns it into a party dress, so the dress evolves through the day."
And while Kate has picked her designer – for the main event, if not the after party – his or her identity is still anyone's guess.
When asked if he’d be designing a dress for Kate, Oldfield played it as coy as ever. He also declined comment to PEOPLE except to say in general, "My aim is not for my dresses to stand out, but for the bride to."
