We Can't Believe How Grown Up The 'Stranger Things' Cast Looked At The Season 4 Premiere

Over the weekend the likes of Sadie Sink, Natalie Dyer and Millie Bobby Brown took to the red carpet in Brooklyn, New York for the upcoming season’s premiere a week before its debut on Netlfix on May 27.

For the occasion, Brown arrived in a corseted Louis Vuitton dress and walked the red carpet alongside her boyfriend Jake Bongiovi, who coordinated her stunning look in a monochrome ensemble of his own. Meanwhile, Dyer wore a gothic Saint Laurent feathered number while her real-life partner and co-star Charlie Heaton sported a neutral-hued suit by Richard James teamed with Gucci loafers.
