When it comes to fashion, Amal Clooney tends to pay homage to decades past [1]. So that's exactly what she did for the Casamigos Halloween [2] party, which took place in LA. Amal showed up and posed for photos by Cindy Crawford [3]'s side, but it's oh-so-clear whose look stole the show.

Read on for a look at how she styled the outfit with a funky pink box clutch and Giuseppe Zanotti platform heels, then shop a few essentials you need to re-create this costume for yourself. We're sure you didn't already have plans to dress up as something better, did you?
