Princess Kate, 41, made her first outing of the year at Wimbledon on July 4 to watch some of the early rounds both from the Royal Box at Centre Court as well as some of the up-and-coming talent on the outer courts. For her debut at the event as the Princess of Wales (a title she was designated in September upon the death of Queen Elizabeth and King Charles' accession to the throne) at the event, she sported a mint green blazer with statement buttons by Balmain with a pleated white skirt and coordinating accessories. The look drew many comparisons to her late mother-in-law, Princess Diana, who was a fan of midi skirts featuring pleats as well as oversized jackets and sweaters.

She stuck to a similar ensemble as her previous tennis outing: a Self-Portrait dress with short sleeves, a waist-defining belt and a pleated midi skirt. Rather than mint, Kate opted for a lime green reminiscent of a tennis ball! When the Princess of Wales headed down to Centre Court to present Marketa Vondrousova with the winner's trophy, part of her role as patron of the All England Lawn Tennis and Croquet Club, she gave an even better look at her head-to-toe look. And in the stands, Kate got a better look at the action sporting Victoria Beckham sunglasses. Kate Middleton attends Wimbledon on July 15.

For the final day of Wimbledon, Kate brought along some family members: her husband Prince William, their eldest son Prince George and their daughter Princess Charlotte. Sticking to the green theme, the princess rocked a Roland Mouret dress in an emerald shade. Kate Middleton attends Wimbledon on July 16.

For each appearance, Princess Kate accessorized with a bow tie pin representing her role with the All England Lawn Tennis and Croquet Club. The pin features the club's official colors — purple and dark green — and is perhaps the inspiration behind Kate's green streak. The pin has been a staple of Kate's Wimbledon wardrobe since she took over the patronage from Queen Elizabeth in 2016. Kate Middleton attends Wimbledon 2022.

The royal has worn green on multiple tennis occasions before — but also yellow, blue polka dots, pink, white and more. Can't get enough of PEOPLE's Royals coverage?

The club's green and purple colors also appear on the hats that are handed out in the Royal Box on especially hot and sunny days. Although hats are typically discouraged in the exclusive seating area because they block the views of other guests, exceptions to the rule are made — and Kate even brought her own headpiece during a summer 2022 outing.
