Today’s TV shows are packed with chic leading ladies—Mad Men’s Megan Draper, Downton Abbey’s Lady Mary, Game of Thrones’ resident platinum-haired ass-kicker Daenerys. But for those who came of age in the early aughts, few onscreen characters compared to the utter fabulousness of The O.C.‘s Marissa Cooper (may she rest in peace).

Even when she was passing out in a Tijuana alleyway or being almost-molested by her on-again-off-again boyfriend’s brother (why you gotta cause so much trouble, Trey?!), the troubled teen always looked flawlessly styled.
