It’s kind of crazy to believe, but it has been 15 years since The O.C. first premiered on TV. Yep, we’re not too far off from it being two decades since we first met Seth Cohen, Ryan Atwood, Marissa Cooper, and Summer Roberts and we’re over here feeling old AF if we’re being honest. Rachel Bilson, the one and only Summer herself, took to her Instagram to commemorate the big anniversary with an epic throwback shot of the cast.

The fashion during this time in history is iconic, the early 2000s was everything. Fun fact about the series though is that a ton of your faves were a part of it before they went on to become big name stars in their own right. Before Bella Thorne was known for her role on Disney Channel’s Shake It Up or for being well, Bella Thorne, she was in an episode of the FOX show when she was a kid. Other unexpected faves appeared on the series too, so get ready for this trip down memory lane before you decided to binge the show again. Check out the gallery below!
