When I first stumbled across The O.C. five years ago, I was immediately hooked. Sure, the storyline was full of dramatic breakups, love triangles, and the occasional over-the-top plot twist (remember Oliver?), but it was the fashion that reeled me in.

On the surface, The O.C. might seem like a showcase for unattainable luxury—designer labels, meticulously curated outfits, and wardrobes that screamed “effortless chic” but probably cost a small fortune. But here’s the thing: those looks? Totally replicable. And with a little creativity, they can be done sustainably too.

Take Marissa Cooper’s bohemian aesthetic. Flowy skirts, layered tank tops, and jackets that somehow made brooding on a beach look stylish—it’s all so timeless. Secondhand shops are absolute goldmines for pieces like this. I’ve found flowy skirts with just the right amount of drama at local thrift stores, and sites like ThredUp make the hunt even easier. You don’t even have to leave your house; scroll through their curated collections, and you’ll be channeling your inner Marissa in no time. Bonus: prices that won’t make you cry into your coffee.

Then there’s Summer Roberts, who is, without question, my personal favorite. Her bold, preppy outfits brought so much color and personality to the show. While she rocked a fair share of designer brands, it wasn’t about the labels—it was about the attitude. The way she effortlessly mixed girly pieces with iconic 2000s trends (let’s all take a moment to appreciate her blue Juicy Couture tracksuit) is what makes her style so fun to emulate. And you don’t have to raid a luxury boutique to nail her vibe.

If you’re looking for preppy staples like pleated skirts or cute cropped sweaters, secondhand is the way to go. Sites like ThredUp or Depop are packed with options, and Etsy is amazing for unique, handmade accessories. Supporting small businesses while getting Summer-approved accessories? Win-win. Personally, I’ve found the coolest bandanas on Etsy—perfect for a quick pop of color when I’m having a bad hair day. Want to mix things up without spending money? Host an accessory swap with your friends. It’s sustainable, and you never know what hidden gems you’ll walk away with.

Even Seth Cohen’s geek-chic wardrobe deserves a shoutout. His band tees, cardigans, and skinny jeans practically scream “thrift me.” Seth’s style is proof that you don’t need to buy new to look cool. Hit up a vintage store or your parents’ closet (seriously, check those attics—you’ll be surprised). His wardrobe is all about personality, and vintage pieces are the most sustainable way to stand out.

What I love most about the fashion in The O.C. is how it feels timeless. Sure, there were a few misses—low-rise jeans paired with questionable belts, anyone?—but even now, 20 years after the show first aired, its wardrobe still inspires trends. Whether it’s the resurgence of low-rise jeans (controversial, I know) or the rise of graphic baby tees, the show’s style legacy remains relevant. If you’re on the hunt for early 2000s fashion inspo, The O.C. is the ultimate blueprint.

What makes it even better is how easy it is to reinterpret these looks in 2024 in a way that aligns with modern values. Fashion doesn’t have to be about excess or exclusivity. It can be about creativity, reusing what we already have, and making thoughtful choices. The characters of The O.C. might have lived in mansions, but their style is accessible to anyone willing to dig through a thrift rack, scroll through a secondhand app, or upcycle an old favorite.

So, the next time you’re rewatching The O.C. and feeling nostalgic for early 2000s fashion, remember: those iconic looks are closer (and more sustainable) than you think. All you need is a bit of imagination—and maybe a good thrift store nearby.
