When it comes to Halloween, there are two kinds of people in this world. There are the people who slap a pair of cat ears on their head and call it a day (me, sorry). Then there are those who don't procrastinate with their Halloween lewk and instead take their spooky season costume very seriously. Celebrities tend to fall into the latter category and make us all want to step up our October game. Does their A+ Halloween aesthetic have to do with the fact that they have tons of resources, including movie studio makeup artists, prosthetics, and just straight-up cash to drop? Sure. (Looking at you, Halloween queen Heidi Klum! ) Still, you have to appreciate their efforts, especially when their costumes are this good.
