Ashley Tisdale Recreates Iconic Sharpay Moments for High School Musical's 20th Anniversary

Ashley Tisdale is still bopping to the top! The actress and entrepreneur, 40, celebrated High School Musical's 20th anniversary by trying on some of her character Sharpay's costumes — which she's been holding onto all this time. "You can take the girl out of East High ... but you can't take the Sharpay out of the girl," Tisdale wrote over a video of herself strutting down the halls of what appears to be a storage unit, wearing a variety of Sharpay's pink-filled wardrobe. In the caption she wrote, "20 years and two babies later I'm still squeezing into these." The first clip shows the star in the blue sparkly dress that Sharpay wears while performing "Bop to the Top" in the first film of the franchise. She also tries on a pink tweed set and another pink outfit topped off with a silver sequin shrug. Fans in the comments are loving the throwback. "OMG, this is so nostalgic 🥹 I love you so much 🤧," one wrote. "Omg!! Watching you in these made my heart so full 🥹🥹🥹🥹🥹," said another. A third wrote, "OMG!!!! 😭🥹 You’ll always be our fabulous Sharpay! 🩷✨" High School Musical was an instant success when it premiered on the Disney Channel January 20, 2006, becoming the most commercially successful of the channel’s original films and generating 7.7 million viewers in its premiere broadcast. The movie’s soundtrack reached number one on the Billboard 200, remaining on the list for more than 100 weeks. The film also spawned merchandise, a successful concert tour, two follow-up films, and a tv series — and launched the careers of the young actors in its cast: Zac Efron, Vanessa Hudgens, Alyson Reed, Corbin Bleu, Monique Coleman and Lucas Grabeel starred alongside Tisdale. High School Musical followed basketball star Troy Bolton (Efron) and brainy new student Gabriella Montez (Hudgens) who meet at karaoke, discover a shared love for singing, and then audition for the school musical at East High. PEOPLE spoke to cast members as well as director and choreographer Kenny Ortega in honor of the movie's 20th anniversary. “When we were shooting the big finale [“We’re All In This Together’] … I took my eyes off the monitor and just took in the scope of the whole room and I thought, ‘My God, if Disney Marketing does the job that we're doing in this room today, we have a juggernaut,’” Ortega tells PEOPLE for an exclusive look back at the franchise in the print edition, on newsstands now.

The cast spoke about the impact that the movie has had on their lives and careers. "It’s extraordinary how deep of a path was carved ahead of me at 15 years old from working on High School Musical," Bleu PEOPLE. "At the time I had already been in the industry for over a decade as a child actor, studying and working towards an undefined dream. It was simply a wonderful and fortunate opportunity to apply a multitude of artistic skills alongside peers."
