Margot Robbie, Paris Hilton, Austin Butler

It’s the spookiest time of the year again and the celebrity costumes in 2023 have absolutely caught our eye. Whether they’re seasoned pros like the iconic Heidi Klum or iconic couples costumes like Hailey and Justin Bieber, Halloween is everyone’s time to shine in the light (or dark for that matter).

The fun is packed this year with celebs gathered at the annual Casamigos Halloween party on October 27, 2023 in Beverly Hills, and at Vas Morgan and Michael Braun’s Halloween Party on October 28, 2023. The star-studded guest list included Kaia Gerber and Austin Butler, Paris Hilton, Megan Fox and Machine Gun Kelly, Justin Bieber, Jodie Turner-Smith, Rande Gerber, and Cindy Crawford. However, there are some restrictions to some celebrity costumes as SAG-AFTRA advised members of the union to not dress up as any TV and movie characters to support the ongoing strike.

So who dressed up or dressed down for their celebrity costumes? See all the pictures here.
