Casamigos Halloween Party  - Arrivals

Cool Moms Cindy Crawford and Amal Clooney Went All Out for Halloween

The '60s and '70s were all about big hair. So when Casamigos Tequila threw its annual Halloween party, this year with a 1970s theme, the hair did not disappoint.

The party, which was held in Los Angeles on Friday, October 27, and was hosted by company founders and the party's ostensible hosts George Clooney and Rande Gerber, was a family affair: their wives, human rights lawyer Amal Clooney and supermodel Cindy Crawford, stole the show with their big, seventies hair and eye-catching outfits.

Crawford wore a colorful dress accessorized with a white fur, and her husband wore a white suit and platform shoes appropriate for any disco. They walked the red carpet together, as did their model kids, Presley and Kaia Gerber.

Presley's aviators seemed to nod to the theme, but rising supermodel Kaia went all-out in a wig, silver-y top and pale blue mini-skirt.

Amal, whose typical look is super-polished, let her hair down (and out!) for the night, rocking a glittery turquoise outfit with massive gold hoop earrings and oversized sunglasses. The Daily Mail identified her top as a sequinned corset from Halpern's SS18 collection. It's unclear whether her husband George made an appearance at the event or stayed home to take care of the couple's new twins Ella and Alexander; he may also have been on the road promoting his new film Suburbicon.

Also at the A-list party was Kim Kardashian West and her friend Jonathan Cheban, dressed as Cher and Sonny Bono, respectively, in bespoke outfits.
