Princess Catherine and Princess Charlotte’s Wimbledon appearance last month—both sporting sunglasses, though not matching ones—got us thinking: what’s the royal protocol around sunglasses? People correctly pointed out that, while Catherine and Charlotte did wear shades while they watched the tennis match, when they met staff, volunteers, ball boys and girls, and others before the match began, they didn’t have sunglasses on. After the match, when they headed inside to congratulate Carlos Alcaraz on his victory, they were also absent. (By the way, you can shop Charlotte's sunglasses, and her entire Wimbledon look, here.)
