10 Sexy Halloween Costume Ideas for 2026

The invite’s gone out, the group chat is already sharing outfit pics, and you still have no idea what you’re wearing. You’re in good company. Every October our stores fill up with people who want to look amazing at a Halloween party but haven’t quite decided how.

So we’ve done the deciding for you. These are our favourite sexy Halloween costume ideas for 2026, picked from the looks our store teams get asked about most. Each one comes with a few easy extras to turn a costume into a proper outfit, and you can shop every look in our sexy Halloween costumes range.

1. The devil

Red, horned and impossible to miss, the devil is the most popular sexy Halloween costume for a reason. It works on everyone, it photographs well, and it gives you a ready-made attitude for the night.

Our Sexy Devilish Costume is a two-piece that does all the work, and at £24.95 it leaves room in the basket for the extras.

Finish the look: a vivid red wig like the Ruby Red Jessica Wig, black hold-ups and your highest heels.

2. The French maid

The French maid outfit has been a classic for decades, and it’s not going anywhere. You can go full costume with the Black French Maid Costume, or keep it lighter with the Flirty French Maid Lace Lingerie Set if you want something you’ll wear again.

Finish the look: white or black stockings, a feather duster, and a sleek dark wig if you want to change things up.

3. The naughty nurse

The nurse is cute, cheeky and easy to wear, which is why it stays near the top of the list every year. The Sexy Naughty Nurse Costume is simple and flattering.

Finish the look: for a scarier twist, pair it with our Blood Stain Opaque Hold-Ups and you’ve gone from nurse to horror-film nurse for under a tenner extra.

4. The night officer

Take charge this Halloween. The Sexy Night Officer & Thong Set gives you the uniform look without the bulk, which makes it a great option for clubs.

Finish the look: a pair of fluffy handcuffs clipped to your belt, aviator sunglasses and knee-high boots. The cuffs might come in handy later too.

5. The wicked nun

A little bit holy, a lot more wicked. The nun is a brilliant choice if you want a costume that gets a reaction without showing a lot of skin. Our Black Sexy Nun Costume does the work for you.

Finish the look: dark lipstick, smoky eyes and fishnet hold-ups. A long black veil and pale skin finish the effect.

6. The bunny

Ears, a tail and a whole lot of attitude. The bunny is one of the easiest Halloween outfits to wear all night, and it suits every body shape. The Black Sexy Bunny Costume keeps things simple.

Finish the look: sheer black tights or seamed stockings, a bow tie and patent heels.

7. The dominatrix catsuit

If cute isn’t your thing, go sleek. The Miss Whiplash Catsuit, in black or red, is full coverage but still seriously sexy. It’s a great pick if you’d rather not worry about hemlines all night.

Finish the look: a riding crop from our whips and crops range, a high ponytail and pointed boots.

8. The gothic queen

For anyone who prefers dark and dramatic to sweet, the Sexy Gothic Dream Costume is made for you. It works for vampire, witch or just a very glamorous goth, depending on how you style it.

Finish the look: a long, sleek wig like the Black Elise Wig, deep red lips and a lace mask.

9. The alien

If you’d rather be the only one at the party in your costume, go out of this world. The Fantasy Roleplay Alien Suit, in S-M and L-XL, is a guaranteed conversation starter.

Finish the look: silver or holographic make-up, a bright wig and platform boots.

10. The “make it yourself” horror look

No themed costume needed for this one. Build your own. Take a black lingerie set you already love, add blood stain hold-ups, a dramatic wig and some fake blood make-up, and you’ve got a sexy horror look that’s completely yours. It’s also the easiest way to wear something you’ll put on again long after October.

How to finish the look

The difference between a costume and an outfit is in the details. Here’s the formula our store teams use when customers ask for help:

• A wig. Nothing changes your whole character faster. Browse our full wigs collection, from bold reds to sleek blacks.
• Hold-ups, fishnets or stockings pull a costume together and make legs look endless. See our stockings and hold-ups.
• Heels or boots finish any look. Just pick a pair you can actually stand in for the night.
• One prop. Handcuffs, a crop, a mask or a duster. One is plenty.

Three or four extras are usually all you need. Any more and the costume starts to get lost.

Sexy Halloween costumes for couples

Dressing up together is half the fun. A devil and an angel, a nurse and her patient, an officer and the person she’s arresting: the classic pairings work because everyone gets the joke straight away.

If your partner’s not big on costumes, keep theirs simple. A matching colour, a single prop or some coordinated underwear is enough to show you’re a pair.

After the party

Most sexy Halloween costumes are made just like lingerie, which means the night doesn’t have to end when you get home. Plenty of couples find that a costume is a fun, low-pressure way to try a bit of role play. If it makes you both laugh, even better.
