Noticeably absent from the collection was the country's national motto that, too, defined the era: Liberté, Egalité, Fraternité . But the overt references didn't stop there. The show notes began with a quote from legendary Vogue editor Diana Vreeland: “The sixties were about personalities. It was the first time when mannequins became personalities. It was a time of great goals, an inventive time… and these girls invented themselves.” Vreeland is credited with inventing the term 'youthquake' in 1965, and it'd go on to be crowned the word of the year in 2017 . It's a term that feels especially pertinent to the today, as it defined the uprising of young people in London in the '60s.
