Prince William and Kate Middleton's three children were treated to a special gift from Wimbledon champion Jannik Sinner over the weekend. On Sunday, the future king and queen of England made a surprise appearance at the iconic tennis match, alongside two of their children, Prince George, 11, and Princess Charlotte, 10.

For her part, Kate Middleton was also a vision—this time in a custom Roksanda dress in an eye-catching blue that is fast becoming the Princess of Wales’s signature hue. It’s yet another reason to love the fashion runway that is Wimbledon. (Kate’s L.K. Bennett straw hat was yet another scene-stealer. Fashion inspo abounds.)

A fan posted a video of the Prince and Princess of Wales and their two oldest kids walking to their seats in the royal box at Wimbledon on Sunday.

Kate Middleton’s latest outing is an ace. The Princess of Wales, 43, attended Wimbledon for the first time this year. She stepped out to watch American tennis player Amanda Anisimova and Poland’s Iga Swiatek face off in the women’s singles final on Saturday.

Kate wore her two eternity bands with her 12-carat oval-cut Ceylon sapphire engagement ring for the first time at Wimbledon.

Maybe it's the 30-year-long memories of itchy wool school uniform, or not finding a style that suits my pear shape, but I have actively avoided pleated skirts for my adult life. The closest I got was a maxi skirt with a chunky belt that I lived in my early 20s (if you know, you know).

Catherine, Princess of Wales, arrived at Wimbledon to a standing ovation, marking a notable public appearance after announcing her remission from cancer.
