Happy Mean Girls Day. To celebrate, let’s take a walk down memory lane and look at the photos of the Mean Girls premiere and advanced screening. The 2004 fashion is on-point (and making a comeback). And the young Lindsay Lohan, Tina Fey, Amy Poehler, Rachel McAdams, and the rest of the cast make me so nostalgic. I’ll never forget seeing this movie in theaters and instantly loving it. However, I don’t think I or anyone else could have ever predicted just what it would become.
