Here comes the bride! Kate Middleton arrived at Westminster Abbey just at 11 am, choosing not to arrive late as many predicted she would. Wearing an Sarah Burton by Alexander McQueen dress with Chantilly lace sleeves. She wore a Cartier tiara dating back to 1936, not the Queen’s tiara as some had speculated. Pippa Middleton escorted the young bridesmaids to the Abbey, wearing a cream colored Alexander McQueen with a cowlneck.
