Marissa Cooper is still the 'O.C.' It girl 15 years later, thanks to her enduring style

Welcome to the O.C. all over again.

The hit Fox teen drama "The O.C." turns 15 on Sunday, Aug. 5, and we're reminiscing about the Cohen family, sunny southern California in the early aughts, the teen anguish, and a particular It Girl: the one and only Marissa Cooper.

When the show premiered in 2003, almost no one realized that Mischa Barton's complex and moody rich girl character would immediately skyrocket to teen queen status. But such is the allure of Marissa, who became a household name and the fashion idol of tween and teen fans across the country.

From her clothes to her hair and accessories, Marissa's "O.C." wardrobe was heavily coveted. And with tube tops and polo shirts paired with denim mini skirts and flared jeans somehow returning to the sartorial landscape in 2018, Marissa Cooper might just be to blame.

The It Girls of 2018 came of age in the height of "The O.C." mania, and their recent style choices are definitely reminiscent of the coolest girl in Orange County.

Kendall Jenner in a tube top? Coop has been there and done that.

Bella Hadid's pastel tank top and jeans might seem on-trend in 2018, but they were also Marissa's trendy go-to look in 2003.

This Victoria Justice look is straight out of Marissa's style playbook, from the slightly cropped shirt to the newsboy hat.

Much like Marissa Cooper, Lucy Hale likes a preppy blazer to play up her style.

Another preppy Marissa staple piece was a polo shirt (sometimes two at a time), which Emma Roberts brought back in light pink.

Even 15 years after her character first hit the small screen, Marissa Cooper's lasting fashion legacy endures in ways we couldn't have predicted with the resurgence of nostalgia trends.
