Pippa Middleton, Kate Middleton

Kate Middleton and her sister Pippa watched Wimbledon men's singles final match on Sunday.

The Duchess of Cambridge and her sister Pippa sat in the Royal Box on Day 13 of the Wimbledon Lawn Tennis Championship in London. The sisters cheered passionately for fellow Brit Andy Murray, who took an early lead, but eventually lost to Switzerland's Roger Federer.

Kate was dressed in a cream jacket and a Vanessa dress by Joseph. After the game, the Middleton sisters stood as Murray made an emotional speech after his defeat.

David and Victoria Beckham were also seated in the Royal Box.

Kate and Prince William attended a few earlier matches of the tennis tournament. 

"I met Kate for the first time, William I’ve met before after Australia,” Federer told reporters after meeting the royal couple. "They were very nice, very friendly.

"Royals coming out, I think it's inspiring, too, in some ways, believe it or not. It's great for the event. It's great for Wimbledon. It's great for the club. It's great for the players."

At the July 4th game, Middleton was dressed in a tennis-inspired dress; a cream-colored vintage sailor dress from Alexander McQueen's 2006 collection, which the Duchess worn almost exactly a year before.

Not to be outdone, Pippa impressed tennis fans with her style, as she watched four-time Wimbledon champion Serena Williams beat Hungary's Melinda Czink.

The 28-year-old stunned in a white and navy, three-quarter sleeved macramé jacket by Orla Kiely, and a navy knee-length dress and black patent leather, peep-toe wedges. 

She protected herself from the sun by wearing black and gold "Obsedia" sunglasses by Givenchy, and completed her look by a quilted white leather purse with a gold chain handle.
