It's a wedding no-no for the bridesmaid to outshine the bride, but Pippa Middleton very nearly could have stolen the show from big sis Kate. The bride's No. 1 lady was absolutely lovely in a sleek, figure-hugging cowl-neck Sarah Burton design (in white?!) that featured the same button details and lace trims as Kate's gown. She kept the jewels to a minimum and her 'do half up and half down. Everyone knew the new princess would be a knockout at the wedding, but Pippa was the big surprise!
