The British actress recently attended the opening night of her fiance Tom Sturridge’s new play American Buffalo. For her part, Miller is set to star in the movies High-Rise and Adam Jones, opposite Bradley Cooper.

For her last turn at the Met Gala, in 2013, the actress perfectly encapsulated the punk theme in a white Burberry gown, studded motorcycle jacket and spike manicure — and she was even snapped kissing Cara Delevingne.
