While Kate Middleton has been busy preparing for her eleven-day tour in Canada and California, her sister was making her own plans as well.

Fashionista and tennis-lover, Pippa Middleton, has been stirring a huge buzz at the 2011 Wimbledon championships with her style statements.

The 27-year-old sister of the Duchess of Cambridge has been looking stunning at the games and receiving wide media coverage.

At the recent men's semi-final match, Pippa was seen in a navy blue crochet dress by Tania and a heavy pair of aviator sunglasses.

Earlier, she was spotted during the quarter-final match between Jo-Wilfried Tsonga of France and Roger Federer of Switzerland. She watched the match in a Hobbs NW3 red colored dress, which she paired with brown platform shoes and a matching Modalu handbag.
