Long before Brie Larson was an Oscar-winning actress, the Room star was a teen phenomenon, appearing in hits like 13 Going on 30, Sleepover, and Raising Dad, and rocking some serious early 2000s fashion on the red carpet.

Larson took the opportunity today to harken back to the age of mini skirts, acrylic nails, and pin-straight hair with one epic #tbt. “I know this is a lot to spring on you unexpectedly. Breathe, sit down and take in that I am wearing ACRYLICS,” she hilariously captioned this sassy red carpet photo from the 2004 premiere of A Cinderella Story.

In the epic throwback, 14-year-old Larson rocks a white tee fittingly emblazoned with a frog in a tiara. Paired with a yellow mini encircled by white hearts, a floral print tote, and talon-like French manicure, the actress looked perfectly happy with her bold look.

This hilarious shot is light years away from the Larson we fell in love with this awards season, rocking classic curve-hugging looks on the red carpet, but her down-to-earth humor hasn’t changed a bit.

Keep doing you, Brie!
