We still can't get over last week marking the 15th anniversary of The O.C., the TV show that defined the teenage years of countless girls and birthed Mischa Barton—the ultimate Noughties It-Girl. Revisiting the old series on this landmark birthday is tempting (we suggest a guilty pleasure re-watch this weekend), but be warned: the outfits haven't aged quite as well as Rachel Bilson has.
From Marissa Cooper's pleated denim mini skirts, three-quarter jeans and rainbow boleros (the horror), to Summer's penchant for printed gypsy dresses and peasant tops (lest we forget her hippie period at college), The O.C. is a masterclass in Noughties style.
Here, we round-up the most memorable looks—the good, the bad and the Highly Questionable. Prepare for fashion whiplash.
