Hilary Duff posts throwback 'Lizze McGuire' pic, proves she hasn't changed one bit

Buzzfeed quizzes aside, there's one true test to figuring out if you were a true 90s kid or not: if your TV time centered around "Lizzie McGuire."

If your answer was an astounding "yes", then you probably know Lizzie's signature style better than anyone. Who could forget those platform flip flops, neon pink crop tops, and of course, the occasional overall or two.

Now that denim jumpsuits are making a comeback, Hilary Duff decided to resurrect one of her character's beloved looks. In her latest Instagram post, the actress even poked fun at the similarities, editing the throwback photo side-by-side to her recent outfit.

Turns out, she really hasn't changed one bit -- aside from the rainbow hair of course.
