The High School Musical franchise may be a decade old, but Ashley Tisdale just reminded us that we’re still all in this together. On Thursday (September 8), the HSM actress ’grammed a pic of her walking her dog. Straightforward enough, right? Wrong. The shirt she’s reppin’ is throwing it way back to her days as mean girl Sharpay Evans.

In High School Musical 3: Senior Year, one of Tisdale’s big numbers was the song “I Want It All,” a.k.a. Sharpay’s unofficial motto. It’s a subtle reference, since she doesn’t address the trilogy in her caption, but fans definitely didn’t stick to the status quo with their comments.

The shirt hails from Signorelli and is available here. Tisdale became the creative director for the t-shirt company last year and actually teased the shirt on Instagram earlier this week, captioning, “I want it all. 😉.”

Hopefully more HSM references will sneak their way onto other t-shirts. After all, Tisdale did keep her wardrobe from the Disney films.
