Billie Eilish in 2020 Grammys

Billie Eilish swept the 2020 Grammys as a 18-year-old phenomenon, winning all four Big Four categories. She arrived in an oversized lime-green Gucci suit with baggy pants and neon hair, embracing her signature anti-glamour, baggy aesthetic that challenged traditional red-carpet norms.
Her rebellious, Gen-Z coolness and wide-eyed authenticity made her an instant icon for a new generation.
