Halloween started a few days earlier for the stars of Hollywood this weekend. Celebrities gathered in costume for the annual Casamigos Tequila party in Beverly Hills on Friday, then kept the party going the following night in Las Vegas. Partial founder George Clooney made an appearance, along with cofounder Rande Gerber, wife Cindy Crawford, and their kids, Kaia and Presley.
Rande and Cindy's family dressed as iconic rock musicians, like Joan Jett and David Bowie. Other guests included Harry Styles in a showy Elton John-approved getup, Nicky Hilton imitating her sister Paris on her 21st birthday, Ryan Seacrest as Karl Lagerfeld, and Jenna Dewan, spotted with a handsome date. Check out the iconic array of outfits from the bash ahead, and make sure you keep up with all the best costumes celebrities have worn so far this year.
