Pippa Middleton wows in Wimbledon-white with husband James Matthews

Pippa Middleton was the picture of summer elegance as she arrived at Wimbledon on Friday to watch her good friend Roger Federer compete in the semi-finals. Joined by her husband James Matthews, Pippa gave a sartorial nod to the players' dress code by wearing a white frock by Étoile Isabel Marant. The chic number featured billowing sleeves, buttons down the front and a daring, plunge neckline and fell just above the knees, showing off her tanned and toned legs.

Pippa, 33, paired the summer frock with a Panama hat and navy patent shoulder bag, and added height to her frame with a pair of nude wedges.

Keen tennis fan Pippa was making her third appearance at Wimbledon this year. She's been cheering on the Swiss tennis star Roger throughout the tournament. Pippa and her mum Carole Middleton are both big fans; he was invited to Pippa's wedding in May, and Carole is known to have an innocent crush on the tennis champ.

Pippa's dress is from Étoile Isabel Marant.

On Friday, Pippa and her husband James arrived at the Royal Box with plenty of time to spare before the match. It comes after the former events planner and her mum Carole were banned from the box earlier this week, after they arrived too late for Andy Murray's match against Benoit Paire. Pippa and Carole were pictured sitting separately, just outside of the prestigious seating area that is traditionally reserved for royals, athletes and VIP guests.
