Who says you need to spend a fortune to turn heads this Halloween? Whether you’re prowling a party, stirring up trouble in the club, or answering the door to trick-or-treaters (bravely, in fishnets), we’ve found you seven of the best sexy Halloween costumes for under £10 – proving that scandalous doesn’t have to mean spendy.
From sultry classics to cheeky twists, we’ve rounded up the best budget-friendly looks that’ll make you the main attraction — without your bank balance screaming louder than the ghosts.
1. The Naughty Maid
A timeless favourite. All you need is a feather duster to twirl between your fingers. Add a pair of lace stockings and your best “oops, did I drop something?” face. Suddenly, you’re not cleaning — you’re causing chaos.

2. The Police Woman
Freeze — you’re under arrest for looking dangerously good. A cheap plastic badge and some mirrored sunglasses will add to the look. Add a pair of handcuffs from the pound shop and your sassiest strut for maximum fun. The only law you’ll be breaking is the one against being too hot.

3. The Naughty Nurse
Stat: 100% of partygoers report higher heart rates around this outfit. Some red lipstick can transform you into the sexy saviour of the night. Add a toy stethoscope and a cheeky bedside manner — no actual medical training required.

4. The Cave Woman
Who needs designer labels when animal print exists? Some tousled hair will have you looking like you just stepped out of a prehistoric love story. You even get a toy club to help win over your future partner.

5. The Bunny
The ultimate in flirty minimalism. Fluffy tail, collar, cuffs, and a pair of bunny ears — done. Add eyeliner whiskers and you’ve got yourself a playful look that’s equal parts sweet and sultry. Don’t be surprised if you hop away with all the attention.

6. The Devil
Red horns, bowtie, tail, and your most mischievous grin. The devil costume is a budget-friendly classic for a reason — it’s fiery, fearless, and fabulous. A cheap trident from the fancy-dress aisle will seal the deal. Add smoky eye makeup and you’ll look hot enough to raise hell.

7. The Cat
Simple, sleek, and guaranteed to slay. All-black outfit? Check. Eyeliner whiskers? Check. Headband with ears? Double check. Whether you’re a sultry panther or a purring kitten, this look is the purr-fect (sorry, had to) way to look effortlessly sexy for under a tenner.

Final Trick (or Treat)
There you have it — the best sexy Halloween costumes for less than £10. With a little creativity (and a lot of confidence), you can turn even the simplest pieces into something wickedly wonderful. Who needs couture when you’ve got charm, cheekbones, and a budget that still allows for a post-party kebab?
