The most frustrating part of the Y2K resurgence is being influenced by teenagers simply perfecting something you already wore. It’s not their fault, of course — they are mere vessels for the trend cycles perpetuated by big fashion businesses to keep us buying more and more. But before we all continue to dive headfirst into ironic tees and butterfly clips, I think it’s important to talk about history. By that, I mean Mary Kate and Ashley Olsen’s 2001 film Holiday in the Sun. This month, the movie (which also stars a young Megan Fox) turns 20. Upon a recent rewatch, I have a theory: This movie is one of the best representations of aspirational Y2K fashion.
