The Best It Girl Halloween Costumes for a Spooky (Fancy) Season

Pinterest reported that searches for “It Girl Halloween costumes” increased 170% this year. Why? Some of us see Halloween as a golden time of year when we can live out our Poison Ivy fantasies, and some of us see it as an occasion to smugly show off our niche IYKYK pop culture knowledge. But for those who don’t feel like dressing up like Moo Deng while dolling up our boyfriends as “finance men” or living out our Marvel cosplay dreams, Halloween can feel like a fast-fashion-filled obligation. That might be why we’re turning to Charli XCX and Hailey Bieber for Halloween costume inspiration. It’s a sustainable approach that also ticks the “get ready in five minutes” box (Charlie XCX = white t-shirt with no bra).

They have the advantage of providing instantly recognizable, warm looks with pieces for your wardrobe that you can wear over and over again.

So, these are the It-girl looks we’re going to be inspired by (and wear in the New Year) this Halloween.

Our Favorite It-Girl Halloween Costumes

Hailey Bieber Halloween Costume

Miss Bieber went viral with her strapless red Ermanno Scervino mini dress in 2023. The look was ’90s perfection with a polished updo, classic “B” pendant and matching Ferragamo bag and Maison Ernest heels. Even better? It’s very easy to copy. We love a large pendant from Mejuri and the Tanya Cut Out dress from More To Come is dorky sweet. Accessorize with the man wearing Crocs of your choice.

Charli XCX Halloween Costume

Our brat queen is all about dirty chaos and has one of the easiest looks to copy, because it’s all about not giving a fuck. Charli is an avowed fan of the white tee or the braless tee, so pick one and pair it with micro shorts, boots, second-day hair, and grunge smoky eyes for party girl style 365.

Sabrina Carpenter Halloween Costume

Want to channel everyone’s favorite short, sweet blonde? May we direct you to our dedicated roundup of Ms. Rose’s best looks. Sabrina Carpenter for inspiration? With Sabrina Carpenter, it’s all about the micro mini, whether it’s a cinched waist and flared skirt or a top with a belly and platforms. And, of course, the hair and makeup (we’ve got all the details on that front).

Olivia Rodrigo Halloween Costume

Olivia Rodrigo is all about ’90s grunge with a pop-punk princess update. Pair your skater skirt with chunky boots or Mary Janes, a slogan tee, and a pop of bright eyeshadow. As fans, we’ve already thought about it and broken down her tour wardrobe for you.

Ariana Grande bunny costume

You can wear this look less, but it’s a Pinterest favorite for a reason. Fortunately, it also requires little effort. You can add a pair of lacy bunny ears to almost any outfit and pair them with a high ponytail and a short skirt. This pair from Pretty Little Things comes with a black lace veil for a spookier look. Wear it in the front or place it in the back.

Bella Hadid Halloween Costume

Everyone’s favorite It-girl has become everyone’s favorite cowgirl in 2024, and Ms. Hadid has been seen everywhere in low-rise pants, midriffs, and Cowgirl hats. It’s a chicer, sexier look than Jessie’s. Toy Storybut no less ripe for a Halloween interpretation. These Lenni lace-up pants serve up just the right amount of cowgirl when paired with a vest and an appropriately oversized hat.
