We don’t know about you, but when we were 13 years old, our biggest fashion statement involved the color of our braces and the temporary hair dye we hoped our parents wouldn’t notice. But Millie Bobby Brown is proving that not everyone makes those cringe-worthy teenage style choices, because she’s already a full-fledged fashion star, and her latest look brings a heavy dose of teen spirit to boot.

The Stranger Things star is already a major fashion player, as she has been the spokesperson for Calvin Klein’s new brand, Calvin Klein by Appointment, since last summer. It’s no surprise that she made an appearance for the brand’s New York Fashion Week show this week, but her cheer-inspired look was so unexpectedly sophisticated, we would actually consider wearing it… even though we’re well past our school spirit days.

The young actress wore a purple crushed velvet Calvin Klein by Appointment jumper with varsity letters, adding a white turtleneck underneath, with a white leather jacket over the top. She topped her look off with white heels, proving that when it comes to fashion, Brown is here to bring it on.

And it turns out, she has worn the look before, rocking the violet jumper for a shoot in InStyle last October with a classic white tee.
