Millie Bobby Brown Slays in a Teeny Red String Bikini

Reporting live from the tropics to remind us that she's still the silver screen It-girl, Millie Bobby Brown made a splash over the holidays in a fire, red string bikini that screams Baywatch. And where did the Stranger Things leading lady post up to show off her absolutely hot look? Why, Instagram, ofc!

The simply stunning timeless triangle-style two-piece popped up on our feeds on December 25 as a part of a holiday card-inspired "Merry Christmas" wish photo from the florence by Mills founder. Millie's top featured an adjustable halter neck and a tie around the torso. A pair of string bikini bottoms with beaded hip ties peeked out from underneath an open-weave, high-waisted crochet skirt. Though the 'grid photo cuts off most of her lower half, we can see from a Christmas tree-filtered IG story the star posted that the asymmetrical hem of the cover-up featured knotted details with tassels hanging down and a ribbed waistband. For accessories, Millie went with a beaded choker necklace, silver ring, and a matching red hibiscus flower placed in her sleek, pulled-back hair. Fans quickly flooded the post with season's greetings for the actress and her boyfriend, Jake Bongiovi, who is a regular in Mill's social media posts.
