Katy Perry and guest dressed as Bill and Hillary Clinton at Kate Hudson's annual Halloween party on Oct. 28, 2016 in Los Angeles.

With Halloween falling on a Monday this year, celebrities had the whole weekend to show off their best costumes.

From Katy Perry's jaw-dropping Hillary Clinton costume to reality star Kylie Jenner's take on Christina Aguilera's iconic look from her "Dirrty" music video and even a few Halloween makeup smart-phone edits, it's hard to choose which one was the best of 2016.

The best part of Halloween falling on a Monday is that you have the whole weekend before to dress up, possibly multiple times. Clearly celebs are just like us, because over the past few days they've been busting out their Hallow's Eve best, from Katy Perry's mic dropping Hillary Clinton to Beyoncé channeling Salt-N-Pepa and Enrique Iglesias just freaking us out.

Here are some of our favorites:

Beyoncé and fam pushed it real good as Pepa from Salt-N-Pepa (Jay Z also got in the throwback mood)
