Sydney Sweeney looked like Hollywood royalty Thursday night at the 35th annual GLAAD Media Awards.

The Anyone but You star walked the red carpet at the Beverly Hilton in a silky, powder-blue gown by Miu Miu that evoked Old Hollywood and classic cinema. The dress featured a scooped, plunging neckline from which a silver crystal-embellished bra with off-the-shoulder straps peeked out. It was the only shimmer on the gown, which was otherwise timeless in its structured bodice and long, flowing train.
