Non-stop nuptials!

It's a good thing that the Duke and Duchess of Cambridge exchanged vows on April 29th, because Kate and Pippa Middleton's schedules have been jam packed with RSVPs for their friends' weddings since.

Kate, who hasn't been publicly photographed in two and a half weeks, stepped out with her younger sis Pippa to celebrate the nuptials of their close friends Thomas Sutton and Harriet Colthurst in Wilton, Wiltshire in England on Saturday.

The Duchess looked red-hot in a scarlet knee-length lace dress and matching fascinator and was joined by her husband Prince William.

Pippa, who had her serious beau Alex Loudon at her side, opted for a grey-and-white floral-printed frock and black fascinator -- a chic and safe bet for the early fall wedding.

Just last week, Pippa attended the wedding of her college chum Humphrey Bowles in the North Yorkshire hamlet of Lythe, where she pulled a major fashion faux-pas. She wore a clingy, knee-length silk green dress -- a color that has long been considered bad luck to wear to wedding ceremonies according to the adage "weddings and green should never be seen."

I really cant understand the big fuss about Pippa, she is not easy on the eye at all and seems to love the paps. But Catherine on the other hand always looks beautiful and classy.

Kate is the embodiment of pure class... she always looks elegant and chic, if there's someone I'd use as my role model to dress she's got to be the one!!

Can someone please explain the royal's addiction to wearing hats. I wore hats back in the 1960s. Do all ladies wear hats to weddings?
