The best celebrity Halloween costumes earn their kudos due to a few factors. First, no clichés. A skimpy cat costume and haphazard whiskers don’t make the list. Second, the actual costume needs to show effort (though we realize not everyone can be Heidi Klum). And third, finally, we may be biased, but we firmly believe no costume is complete without a head-turning use of makeup and face paint. After all, whether you’re a Halloween fanatic or prefer to “trick-or-treat” from the comfort of your couch (i.e., eating candy corn while watching Hocus Pocus), anyone can appreciate the shock factor of seeing your favorite celebrity transform into a (very fierce-looking) corpse (hi, J.Lo). Ahead, you'll find the best celebrity Halloween costumes, all with mind-blowing makeup looks involved. From J.Lo to Heidi Klum, keep scrolling to see them all!
Of course J.Lo makes being a skeleton look utterly glamorous and drop-dead gorgeous.
Poppy Delevingne makes being a slightly crazed supervillain look surprisingly chic.
Heidi Klum is known for her mind-blowing Halloween transformations, and she shocked everyone with her real-life take on the super-sultry Jessica Rabbit.
This photo surfaced on the internet last year, with no explanation of the occasion, though we like to imagine Lima gracing a Halloween party with this stunning corpse bride costume.
Rihanna dubbed this undead costume Shy Girl for reasons unknown. Regardless, we can’t stop staring.
A little bit of Make Up For Ever’s Silver Glitter ($15) and some silver face paint go a long way toward crafting this ice queen look from Michelle Trachtenberg.
Leave it to Teigen to pull off a Toddlers & Tiaras costume with aplomb, complete with sky-high wig.
We’re not exactly sure what Allen is supposed to be—a caterpillar? Reptile? Alien?—but we appreciate the excessive sequins and green body paint nonetheless.
Hathaway’s Cleopatra costume might seem tame compared to the rest, but we give her major points for the wig, the lashes, and the elaborate headpiece.
Oh, Iggy, can we just be you already? The rapper channeled her inner Disney villainess with black-and-white everything, complete with a live Dalmatian (because obviously the costume wouldn’t be complete without one).
Grimes channels Frankie Stein from Monster High in 2012 for a welcomed new take on the standard schoolgirl costume.
Trachtenberg showed up at Heidi Klum’s annual Halloween party in 2011 with blue body paint, an orange wig, and crazy false lashes—a next-level creepy doll costume if there ever was one.
Leave it to Osbourne to pull off a particularly realistic Carrie (this one might just haunt our nightmares).
We had to list Klum in this list twice, because this incredibly realistic costume of her senior-citizen self always takes the cake.
Which of these looks is your favorite? What’s the craziest costume you’ve ever pulled off? Tell us below!
