From Hydro Flasks to scrunchies, these are the items every VSCO girl will want this holiday season

Birkenstock has had a major renaissance among fashionistas in recent years, finding its way into the closets of some of the most stylish women after the shoe was initially heralded as a hippie essential in the 1960s.

VSCO girls have not been immune to the Birkenstock craze and are constantly seen wearing them on social media.

Though"Sex and the City"'s Carrie Bradshaw once said "no woman … would be caught dead at a hip downtown restaurant wearing a scrunchie," the '90s accessory has made a major comeback, and VSCO girls are largely to thank.

Created by Southern California friends Giffin Thall and Paul Goodman after a trip to Costa Rica, Pura Vida is essentially the updated version of the classic friendship bracelet. And VSCO girls cannot get enough.

Slip-on Vans have been flying off the shelves this year, Bloomreach found, largely as a result of VSCO girls looking to complete their hybrid surfer/skater girl look. From October 2018 to October 2019, purchases increased by 109%, according to Bloomreach.

Similar to Birkenstock, Crocs have made a significant comeback as of late, with legions of adoring fashion fans and a celebrity face in the form of seminal manic pixie dream girl Zooey Deschanel. Turns out, VSCO girls are also fans.

One of the most telling indicators of a VSCO girl is her brightly colored Hydro Flask — a vacuum insulated stainless-steel water bottle — which she will inevitably be toting and sipping from across social media.

Hydro Flask knows how to play to its audience — even its Instagram page is filled with VSCO girls — and as a result purchases have increased by 239% in the past year, according to Bloomreach data.

VSCO girl is a lifestyle, but it's also a movement — many of these young women rally around environmental causes. In addition to their love of the Hydro Flask, VSCO girls are also passionate about replacing plastic straws with reusable models. Bloomreach found that sales of reusable straws increased by a whopping 357% in the past year.
