<b>Designer of the dress</b> 

Giles Deacon has been at the top of the list for potential wedding dress designers for Pippa since he was spotted arriving at her house with dresses in November. When it comes to if he has secured the job, Giles remains mum. 

"I can never really comment on rumors," he told HELLO! Fashion while promoting his new Ariel and Giles Deacon Eek! collection. "Until things are confirmed it's just rumors." 

One thing he did confirm was his approval for Pippa and her big sister Kate's style. "I think they've both got divine style. They're thoroughly modern girls promoting British brands and looking fantastic."
