The Don't Worry Darling star, 38, toasted the "As It Was" singer's final concert at New York's Madison Square Garden on Wednesday, wearing a plunging Stella McCartney cut-out dress. The floor-sweeping gown matched the boho vibe of Harry's House, with a circular keyhole detail and spaghetti straps. Wilde paired the look with sky-high platform boots from Casadei and Anita Ko gold jewelry, the New York Post reports, and a white feather boa — a gift to concert-goers — which she rocked from her perch on the arena's floor. Wilde's appearance at the show followed a taping of The Late Show with Stephen Colbert, in which she promoted her new movie, which stars Styles, 28, and Florence Pugh. While the actress and director has made a practice of supporting her boyfriend's career, he has often had an influence on her fashion choices.
