Leave it to the Queen in the North to show up to her husband's ex-girlfriend's SNL party looking like a ray of sunshine—and debuting one of this season's top trends. On

Saturday night, Sophie Turner and Joe Jonas celebrated Taylor Swift's appearance on the weekly comedy show alongside Blake Lively, Ryan Reynolds, Cara Delevingne, and Anya Taylor-Joy. For the occasion, Turner wore a black leather shacket from Nour Hammour, a matching Louis Vuitton mini bag, and a bright-yellow two-piece suit from Camilla and Marc. But while we'd be happy to copy her entire look, the tailored co-ord is what we really can't seem to forget.

Turner's suit featured a slightly boxy waistcoat with matching wide-leg trousers, a look that's been growing in popularity for the last year. In fact, the Game of Thrones actress is but one of many celebrities who have been spotted wearing the suiting combination, including Kendall Jenner, Bella and Gigi Hadid, and Emily Ratajkowski. The trend was also seen on the streets outside of shows during S/S 22 fashion month, in Paris, Milan, New York, and London. Before long, it'll be everywhere.
