The singer and actress looked beautiful in a custom silk ruby-red Armani Prive pleated frock embellished with black crystal flowers.
Her look has been described as effortless, cute and 'very Billie.'
"Arriving at this year's ceremony, the singer stayed true to usual style M.O. wearing oversized separates that consisted of a boxy black blazer, which was layered over a blue striped button-down, and a long and loose khaki skirt," Instyle reported.
"The most Billie thing about her outfit, however, was the red ruffled socks she wore with her black Mary Jane heels, turning the typical fashion faux pas into a red carpet statement. During her time on the red carpet, Eilish revealed that she'd gotten the shoes at a thrift store."
