Pippa Middleton's Birthday: A Look Back At A Year Of Style (PHOTOS)

Happy birthday, Pippa!

Today the famous Middleton sis turns the big 2-8 and to celebrate, we're looking back at a year of Pippa Style.

Although it may have been her 28th year, this was really the beginning of Pippa Middleton as we know her. On April 29, as everyone awaited Kate Middleton's big arrival at her Royal Wedding to Prince William, the world got a surprise in the form of maid-of-honor Pippa and her perky derriere.

Since then the world's gone mad for Pips and her enviable figure and style. From magazine covers and replicas built from food to an adult film offer and a made-for-TV special, Pippa Middleton has gotten the royal treatment in 2011.

But, of course, we love Pippa most for her style -- chic and simple, on-trend yet timeless. The sleeveless shift dresses, shiny designer sunglasses, luxe leather bags and sophisticated flats (along with permanently bronzed skin) have become this famous sister's signature look.

Take a look below at our favorite Pippa looks from this past year!
