Kate and William's appearance on Wednesday comes after the couple visited University of St. Andrews in the afternoon, where they met 20 years ago and fell in love. “20 years on—it was great to return to St Andrews to see fantastic projects that support the physical and mental health of young people,” the couple wrote on their Instagram.

The couple spoke to students there about how they have been coping during the coronavirus pandemic. Kate dressed more casually for that outing, wearing a Holland Cooper blazer, Veja sneakers, an Erdem striped sweater, and skinny jeans.

Kate originally wasn't planning to go to St. Andrews but changed her education plans to put herself in William's path. “Kate was very strategic,” The Crownhistorian Robert Lacey told ELLE.com in November. “She gave up her place at one of Britain’s premier universities, Edinburgh, and opted for another one [St. Andrews] that probably didn’t have the same academic standard. She had already been to Edinburgh to get her flat accommodations sorted out but switched universities and switched her courses to history of art because that was William’s. She delayed her own education by a year and even takes the chance she won’t get into St. Andrews.”

Ultimately, Kate won William's heart but had to wait nine years for him to propose. “Kate eventually accepted the idea that she would have to do a long apprenticeship,” Lacey recalled. “William didn’t want to marry until he was 30. She waited nine years, but, in the end, she got him at 28, so there’s another strategic accomplishment on her part—and she is proving to be an ideal heir to the throne.”
