Barack Obama's daughters attend Billie Eilish's party dressed in Wild West style

Former US President Barack Obama's daughters, Sasha and Malia, showed up at Billie Eilish's star-studded party in Hollywood dressed in Wild West style.

Malia, 26, opted for a denim miniskirt, a white tank top, and thigh-high boots. She completed the look with a black cowboy hat, a snake around her neck, and a white armband.

Meanwhile, Sasha, 23, wore a much more subdued outfit—a blue top, striped mini-shorts, and brown leather boots.

The "Bad Guy" hitmaker's party was attended by many other celebrities, including model Kaia Gerber, rapper The Kid LAROI, and actress Kiernan Shipka.
