She wore a dress with a bold flower print, topped off with a bolero jacket.

Rather than matching her big sister, Pippa wore a printed dress under a silky, bright olive jacket.

Meanwhile, Pippa Middleton stunned in a ruffled peplum shift dress with a ditsy swallow print.

Princess Catherine wore a blush-pink mid-length dress by Alexander McQueen and a matching fascinator.

Attending Wimbledon that year, Princess Catherine once again proved her commitment to minimalist styling and block colors.

It was another boho-adjacent look for Pippa, in contrast to the demure sophistication of her older sister.
