From devilish corsets to ironic icons, these onscreen Halloween costumes prove that spooky season is also the sexiest season. There’s no denying it… Halloween is the one night where movie characters (and let’s be honest, most of us) get to lean into alter-egos, embrace fantasies, and wear outfits that toe the delicious line between costume and lingerie. From the sulky sarcasm of Easy A to the flair of Climax, these sexiest Halloween movie costumes have become iconic, provocative, and sometimes surprisingly empowering.

The film’s climactic Halloween party scene isn’t just genre-defining—it’s packed with flirty, ‘90s-coded costumes like cheerleaders, sexy doctors, football jocks, and yes, terrible Ghostface robes. While Sidney is the grounded final girl, the party is full of costumes designed to tease and titillate. Tatum especially brings major Halloween thirst energy with her look.

Buffy’s cheerleader Halloween get-up is a pitch-perfect parody of the slasher archetype: tight top, short skirt, and maximum bounce. It’s played for laughs (and for horn-dog horror nerds), but Elizabeth’s camp charm makes it one of the film’s most perversely iconic looks.

Regina George rules the Halloween party in a strapless corset, thigh-highs, and tall bunny ears, turning a simple costume into a bold power move. The look is pure queen bee: sexy, attention-grabbing, and Instagram-ready. It’s the ultimate example of the “just add lingerie” Halloween trend, and it’s been iconic ever since.

At a twisted Hollywood Halloween party, Kirshner channels silver screen glamour with a macabre twist. Her vintage starlet look—satin, curls, and dangerous allure—becomes a morbid sex symbol costume in a film that blurs noir with nightmare. It’s old-school sexy with a fatal edge.
It starts innocent enough: Laurie dons a short red dress and cloak for a Halloween night out with her girlfriends, dressed like fairy-tale ingénues in heat. But when her own twisty tale unfolds (no spoilers, but she definitely isn’t waiting for a man to complete her), her sexy red riding hood costume becomes a feminist werewolf fantasy. This one's a genre-flexing classic among the sexiest Halloween movie costumes.

Worn to a house party on Halloween night, Olive turns her social exile into a sex-positive mic drop by showing up dressed in a black corset with fishnets and a stitched-on red “A” à la The Scarlet Letter. It’s sultry, witty, and subversive, highlighting how Halloween can be the perfect time to rewrite your own narrative, preferably with cleavage.
So next time you’re picking a costume, ask yourself: scary, sexy, or subversive? Movie magic says… you don’t have to choose.
