Designed by the same designer that designed Kate's wedding dress, the Alexander McQueen sheath has attracted a lot of Internet buzz in the hours after the official ceremony. A form-fitting A-line, the ivory gown featured a few of the same small details as the bride's wedding dress, including the row of small buttons down the back.
Like her sister, Pippa Middleton wore her hair in a half-up, half-down flowing style as well. As maid of honor, she was responsible for watching over and arranging the train on her sister's wedding dress, among other duties.
