Keen tennis fan Pippa was invited to sit in the royal box to watch Scotsman Andy Murray take on Croatia's Ivo Karlovic.
The Duchess of Cambridge's sister wore a navy skirt teamed with a navy and white macrame jacket by Orla Kiely – also one of Kate's favourite designer.
Pippa has worn the Irish designer before, most notably when she took part in the Diamond Jubilee river pageant.
This isn't the 28-year-old's first year in the royal box. Last year she sat in the enclosure with her boyfriend at the time Alex Loudon, and her parents Michael and Carole.
Carole was at the tournament this year again, but sat in the regular seats with some friends to watch Roger Federer.
Prince Charles and the Duchess of Cornwall were at the same match, having a whale of a time with Bruce Forsyth and his wife Wilnelia-Merced Forsyth.
