Kim Kardashian West showed up to George Clooney and Randy Gerber's Casamigos Halloween party on Friday dressed as Cher. And on Saturday, she received the ultimate costume endorsement: approval from Cher herself.

The reality star's ensemble was a recreation of Cher's look from the 1973 Oscars, during which she presented the award for Best Original Song alongside then-husband Sonny Bono.
