Billie Eilish took the stage at the 67th Annual Grammy Awards for a performance dressed in an outfit from Martine Rose's latest collection. On Sunday, the 23-year-old performed a smooth rendition of her hit single "Birds of a Feather" wearing a yellow jersey from the clothing brand's Autumn/Winter 2025 collection .

Billie Eilish’s coveted wardrobe often errs on the side of "effortlessly cool." By opting for laid-back separates designed with relaxed silhouettes, the singer-songwriter consistently masters the art of balancing fashion and function.
