The best sexy Halloween costumes to shop this spooky szn
Because saucy is better than scary, no? 🔥👻
We love spooky szn to death (haha, get it?), but we have to admit, we’re bigger fans of sexy Halloween costumes than scary ones. As the Mean Girls mantra goes: In Girl World, Halloween is the once-a-year opportunity to dress up as saucy as you like with zero judgment. So, whether you’ve been inspired by the gothic noir of Catherine Zeta Jones as Morticia Addams in Wednesday, or want an excuse to channel your inner Anna Faris in House Bunny, we’ve got ya covered.
Cosmo’s fave sexy Halloween costumes to shop in 2025
Traditionally, sexy Halloween costumes are all about vampiric vibes, red devils and catsuit-clad superheroes. However, celebrity Halloween costumes are constantly serving up fresh inspo, and anything from glittery Tinkerbell ensembles and sheer, fembot looks to Bridgerton-inspired belles are fair game. If you wanna play dress-up, but don't want to be pinned down by a specific theme, why not find an outfit that you think is super fun, like a cheerleader, a sailor or a classic bunny? In short: you do you, boo.
Keep scrolling for 25 of the best sexy Halloween costumes to shop in 2025.
Take inspiration from Mean Girls' Regina George or The House Bunny’s Shelley. Ann Summers' costume comes with all the accessories – collar, cuffs, ears and even a fluffy tail. We're obsessed with the hot-pink hue, but it also comes in baby pink in sizes XS to XXL.
Ooh la la! You can never go wrong with a sexy maid outfit for Halloween. We love how this costume from Lovehoney comes with a cute lace headband and miniature apron, too.
Attention, troops! An army girl costume is a classic that you can wear for fancy dress parties all year round — we love a fit that gives us cost per wear.
If Bridgerton fever has well and truly got you in a chokehold, why not cosplay your society debut this Halloween? Just add a tiara, a dainty necklace, and elbow-length satin gloves and get ready to be crowned the diamond of the season.
This sexy take on the classic skeleton Halloween costume is just TDF. Even better, this baby comes complete with the matching gloves and stockings. Just grab your favourite heels and you're ready to party.
Ahoy, mateys! Rock someone's ocean in this super-sexy sailor costume. We love that this comes with a little sailor's cap.
We think our gal Bridget Jones would approve of this cute bunny costume that comes complete with matching ears and a tail. The velour bodysuit is hot, but the sheer mesh details offer a touch more coverage (not to mention support for bigger-busted gals who NEED to wear a decent bra). Plus, it comes in sizes S–4X.
This sexy number will double up for Halloween parties and Oktoberfest events. It's available in both red and green colour-ways in sizes XS-XXL. Prost!
Fever Women's Red Riding Hood Costume, Dress and Hooded Cape
Little Red Riding Hood, anyone? Check out the tie-up corset wait and cute cropped cape on this costume.
Hey, Barbie! You’ll look so gorg in this bright pink cowgirl costume, inspired by the blockbuster 2023 Barbie movie.
Ah yes, a superhero-inspired look never goes amiss. Also, we're a big fan of the leotard silhouette, it’s giving that extra somethin' somethin'.
One of the most versatile sexy halloween costumes in our edit is this wet-look catsuit from Lovehoney. It will work for multiple characters come Oct 31 — just add a mask for a saucy superhero look, or whiskers and lil' cat ears for a flirtatious feline fit.
The Queen of Hearts from Alice In Wonderland was basically the OG villain and is hella iconic. We love this sexy take on the traditional 'fit complete with choker, crown and chequered socks.
Channel Carey Mulligan in Promising Young Woman with this sexy nurse costume. Just add a rainbow wig and you're good to go.
Go one step further than the minimalist catsuit with this Catwoman outfit from Forever Young. It's slashed to look like you've been fighting villains and comes with a super realistic mask.
Well ain't this fairy look just the cutest? We're crazy about the corset waist and those pretty wings.
Forget Alice in Wonderland, the dark Mad Hatter is so much creepier. This costume comes complete with Harlequin diamond tights, a checkered bow tie, tutu dress and a top hat with bunny ears attached.
Were you obsessed with Bring It On when you were younger? If so, this could be the costume for you.
Here's a slightly more tradish feline costume, complete with cat ears and padded tail.
Rubie's Suicide Squad Ladies Harley Quinn Joker Costume
Of course, Harley Quinn deffo made the list with her high ponytails, heels and two-tone baseball jacket. Bat not included.
