Billie Eilish in Ralph Lauren at 2028 LA Olympics Handover Celebration

Billie Eilish put a casual spin on a preppy staple while performing at the 2028 Los Angeles Olympics handover celebration on Sunday. Following the closing ceremony of the 2024 Paris Games, the spectacle features performances from fellow Los Angeles natives Snoop Dogg and the Red Hot Chili Peppers.

Eilish, who performed alongside her brother and music producer Finneas, wore a Ralph Lauren polo shirt emblazoned with blue and red stripes and an American flag patch. The singer also added on a pair of khaki cargo shorts, accessorizing with Nike sneakers, argyle socks and a striped denim cap. A silver Chrome Hearts dog tag necklace and rimless frames completed Eilish’s ensemble.

Finneas also sported Ralph Lauren, pairing a navy double-breasted blazer with a striped button-up, baggy khaki pants and black sneakers. A faux lifeguard station with a graphic reading “LA 28” served as the duo’s stage.

During the closing ceremony, the Mayor of Paris, Anne Hidalgo, passed the Olympic flag to Mayor Karen Bass of Los Angeles. H.E.R. performed “The Star-Spangled Banner” in a crystallized Ralph Lauren suit, while Tom Cruise descended into the Stade de France via wire — an obvious reference to major Hollywood productions like “Mission Impossible.”

The closing ceremony for the 2024 Paris Olympics took place on Aug. 11. Entitled “Records,” the spectacle paid tribute to Ancient Greece’s influence on the modern-day Games. Featuring performances by Phoenix and French opera singer Benjamin Bernheim, the ceremony also honored the passing of the Olympic flag to the host city of the 2028 Games, Los Angeles.
