All eyes were on Prince William and Kate Middleton this morning as the future King and Queen of England exchanged vows at Westminster Abbey. But a few guests stole the couple's spotlight even if only for a moment.

The Royal Wedding has been touted as the "biggest fashion show on earth," and from the looks of it, every attendee took their invite as a chance to channel their inner fashionista. While Middleton stunned in a dress by Sarah Burton for Alexander McQueen, gorgeous hats of all shapes and sizes sat perched on heads as far as the eye could see.
