Men's Halloween costumes

Ready to be the scariest and coolest man on the block? We've got a broad selection of outfits for those who dare to go all out and those who prefer subtlety. Choose from classic skeleton costumes or bold & colourful designs to really get you in the mood. Put on your best Dracula accent with a vampire costume, and you'll have everyone around you smiling. Don’t forget to accessorise with costume accessories like blood and false teeth for a fang-tastic time.

Want to get into cosplay this Halloween? Try out our best Rubies character fancy dress costumes, where you can find Superman, Batman and other Marvel designs.

If a full costume feels too daunting, opt for a simple wig or a scary mask, so you can join in on the fun without feeling overwhelmed.

Women's Halloween costumes

For the ladies, we have some of the most popular outfits on the market. Whether that's a glamorous witch costume or a bone-shaking zombie outfit, you'll have no issues finding your favourite fit at wilko. If you've got something a little less creepy in mind, you'll find all your favourite characters within this collection. From Barbie and Batgirl to Superwoman and Harley Quinn, you can select from various recognisable fancy dress outfits.

Hosting your own Halloween party? We’ve got some fantastic Halloween decorations to create your own haunted house. Why not get the kids involved with our kids Halloween costumes - we’ve got the entire family covered!

Our fancy dress sizes explained

Our men’s range covers sizes from small to extra large, so you're sure to find the right fit for you. Our outfits for women come in sizes extra small all the way up to large, making it easy to find a Halloween costume that fits just right. The most important thing is to double-check the measurements on each product so you can compare it to your typical UK size.
