Pippa Middleton gave a big grin to the crowd as she traveled from Westminster Abbey to Buckingham Palace following the royal wedding ceremony this morning. The maid of honor sat with little bridesmaid Margarita Armstrong-Jones in the carriage after watching her sister marry Prince William. Best man Prince Harry got playful during his carriage ride while William and Kate led the procession. Pippa did an impressive job taking care of Kate's 9-foot-long train for the walk down the aisle and getting into their ride, all while wearing her own stunning white Alexander McQueen. The bride and groom will soon be making their way on to the balcony for that special first kiss.
