Each year, celebrities and royals show up in their finest courtside outfits at Wimbledon. Kate Middleton, the patron of the All England Lawn Tennis Club, is a regular at the tournament—as is her sister, Pippa Middleton.

And this year, Pippa was spotted attending with her husband, James Matthews, on day ten of the tournament. For the day out, Pippa wore a pale yellow dress designed by Luisa Kelsey called "The Balmoral." As the brand notes, "The Balmoral is made in England from our signature Broderie Anglaise. This year we have introduced a pale yellow which is wonderfully summery, flattering and wearable and works as easily in the UK as abroad."

The designer posted on Instagram, "A great honour to see Pippa Matthews wearing the Luisa Kelsey Balmoral dress at Wimbledon today."

Balmoral, of course, has deeper meaning for royal fans. It refers to Balmoral Castle, the royal family's residence in Scotland—the Castle was famously Queen Elizabeth's favorite place, and she spent every summer vacation there. "I think Granny is the most happy there. I think she really, really loves the Highlands," her granddaughter Princess Eugenie said of Queen Elizabeth at Balmoral in the documentary Our Queen At Ninety. Indeed, one of the last photos taken of Queen Elizabeth with her great-grandchildren was snapped by the Princess of Wales at the property last summer.

While it's unclear if Pippa herself has ever stayed at Balmoral with her sister, her husband's father David Matthews owns Glen Affric, a Scottish estate. So Pippa is definitely familiar with a Scottish family vacation!
