It’s not an exaggeration to say that early 2000s TV series The O.C. was a fashion sensation—defining the wardrobes of countless teenagers and birthing Mischa Barton—the ultimate Noughties It-Girl.
Even years after it first aired, revisiting the old series is an enjoyable experience (we suggest a guilty pleasure re-watch this weekend), but be warned: the outfits haven’t aged quite as well as Rachel Bilson.
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.
