Millie Bobby Brown is ditching the dark side. The Stranger Things star has gone blonde and it’s very Britney Spears-coded.

In the show, Brown plays Eleven, a girl with supernatural powers, and, yes, brown hair. Could Brown's new blonde look be a sign that she's already working on a new Y2K-coded project? Time will tell.

Her dress gives the 1999/early Y2K aesthetic ... Kim's holiday hair. For glam, the SKIMS founder went with a dark, smoky eye and nude lip, adding a touch of "elegant goth" to the finished appearance.
