This isn't the first time the singer has thrown it back to the iconic look.
Even Britney Spears is obsessed with her "Baby One More Time" schoolgirl look.
The 35-year-old singer took to Twitter on Friday to share a video of her latest at-home fashion show, which included a classy, white number, a cowgirl-inspired look and an homage to the music video of her first big hit.
"???," Spears captioned the video.
Friday's fashion fun wasn't the first time the mother of two has thrown it back to one of her iconic looks. Spears sported the schoolgirl get-up with James Corden in her "Carpool Karaoke" segment last year.
