Is Alice Temperley Creating Dress for Royal Wedding?

April 4, 2011— -- A new fashion frenzy has broken out after Kate Middleton's sister Pippa and mother Carole were spotted at Alice Temperley's London boutique. The designer greeted them warmly and the two women spent several hours at the showroom, according to the Daily Mail. Now the British designer is the focus of fevered speculation that she's the one designing Pippa's maid-of-honor dress, and perhaps Kate's wedding dress.

"It's usually tradition that the bride will choose the same designer for the bridesmaid dresses," Lindka Cierach, Sarah Ferguson's wedding dress and bridesmaid dress designer, told ABC News.

Kate has worn Temperley before – most notably in December 2010, just after she and Prince William announced their engagement. Kate turned up at a charity event wearing a black and white silk chiffon frock from the designer's 2009 collection, teamed with a black blazer.

Temperley has dressed a number of high-profile brides including Milla Jovovich and Emilia Fox. The designer told Vogue UK she strives to "make the bride look beautiful, not to chase or create trends."

If Alice Temperley is now sneaking over to the Palace for clandestine fittings, it won't be the first time she's set foot there. The queen granted the designer an MBE (Order of the British Empire) in March 2011 for her services to fashion. Reportedly, Temperley forgot to curtsey after receiving her honor.
