Pippa Middleton's Style Evolution Through The Years

The Duchess of Cambridge's little sister has made headlines with her fashion choices.

Kate Middleton, aka Catherine, Duchess of Cambridge is known for her sense of style. But her little sister, Pippa Middleton, has made her mark on the fashion world as well.

As maid of honor at her sister’s wedding to Prince William in 2011, she made headlines with her figure-hugging, cowl-neck gown designed by Sarah Burton of Alexander McQueen. She has also been a regular chic fixture at Wimbledon each summer and showed off her lovely maternity style in 2018 while pregnant with Arthur, her first child with husband James Matthews.

In honor of her birthday on Sunday, we’ve rounded up photos of the royal sister’s fashion moments. Keep scrolling for Pippa Middleton’s style evolution through the years.
