Pippa Middleton looked gorgeous at the royal wedding today, acting as the maid of honor for big sister (and now princess) Catherine. Pippa's hair was done at the Richard Ward salon and was loosely pulled back into a half-up, half-down style, with a deep side part and flowing curls down her back. The coiffure was adorned with an elegant floral hairpiece made of ivy and lily of the valley, perfectly matching her sister's bouquet, as well as the wreaths worn by the young bridesmaids. I love that the sisters wore their hair similarly; it showed a very subtle but touching camaraderie. What do you think of Pippa's pretty hairstyle?
