The “Young and Beautiful” star walked the red carpet in a custom beige gown designed by Alexander McQueen’s Seán McGirr, and the one-shoulder dress was lined with what appears to be branches down the entire bodice. The branches stretched into a headpiece with a beige mesh veil draped across her face. She accessorized the outfit by holding a single red rose.

The event’s dress code is “The Garden of Time,” inspired by a 1962 J.G. Ballard short story of the same name.

This year’s theme, Sleeping Beauties: Reawakening Fashion, is set to feature 250 items from the Costume Insтιтute’s permanent collection, according to an Instagram post announcing the theme back in November. “From a 17th century English Elizabethan-era bodice and Christian Dior’s famous Junon and Venus ballgowns, to 21st century acquisitions by designers including Phillip Lim, Stella McCartney, and Conner Ives, the core exhibit will span 400 years of history,” the caption reads.

LDR hung around the Indio Valley after Coachella to make two unannounced appearances at the Stagecoach Festival, last weekend. While there, she joined Paul Cauthen on stage for a moving rendition of “Unchained Melody,” the classic ballad that became an iconic hit for the Righteous Brothers in 1965.

Del Rey, who is prepping a country album called Lᴀsso, sang “Unchained Melody” last year for NBC holiday special celebrating the legacy of Elvis Presley, Christmas at Graceland and Cauthen previously covered the song with masked country crooner Orville Peck, with the pair calling themselves The Unrighteous Brothers.
