Kate Middletondazzled in a blue polka dot tea dressat Wimbledonon Tuesday — a chic yet meaningful choice.

This year, Ralph Lauren redesigned the uniforms for chair umpires, line umpires and ball boys and girls in partnership with The All England Lawn Tennis Club to embrace more sustainable and innovative fabrics using recycled materials.

Kate accessorized her outfit with a few more recycled items from her royal closet, including her Finlay Henrietta sunglasses,recently worn on tour in the Bahamas, and her Mulberry Amberley bag in white, which she has used numerous times before.

Prince William, Duke of Cambridge and Catherine, Duchess of Cambridge arrive in the Royal Box on Centre Court during day nine of The Championships Wimbledon 2022 at All England Lawn Tennis and Croquet Club on July 5, 2022 in London, England.

And the finishing touch was a green and purple bow tie pin, signifying her status as patron of the All England Lawn Tennis Club. The club’s official colors are dark green and purple, and only a few select people — including the club’s president, the committee of management, vice presidents and four members of executive staff — are permitted to wear the bow.

The Duchess of Cambridge is known for her habit ofrecycling previously worn clothing— sometimes evenyears apart! — and she also turns to vintage items. During her Caribbean tour in March, Kate sported a1950s dressfrom U.K. boutiqueWillow Hilson Vintage.

“It was so apt, because it’s got all the great Caribbean colors, it’s such a reggaeton kind of dress in its color palette — she looks like she is having a whale of a time!” Willow Hilson, the founder of the Cheltenham-based independent boutique, previously told PEOPLE.
