While many people like to dress in cute or sexy costumes, Halloween is traditionally about all things dark and spooky. So, if you want to stick to the roots of All Hallows Eve and dress to scare, we're here to help.

We've rounded up the creepiest costumes for this year that are sure to impress your friends. We've also gathered the best online retailers to shop the looks, so that you can get organised sooner.

Scariest Halloween costumes for 2021

1. Kayako Saeki (The Grudge)

With the new The Grudge movie still fresh in their minds, your friends are sure to get a chill when Kayako Saeki comes knocking on their door. Paint yourself white, add a long black wig and prepare to creep out your unsuspecting victims.

2. Hazmat zombie

Embrace the horror of 2020 with a pandemic-inspired hazmat suit that can be easily paired with a protective face mask. If you want to step things up a notch, you can make it extra creepy with blood stains or some killer zombie makeup.

3. The Invisible Man

This one may take some extra effort, but we promise it will be worth it. Invest in an oversized suit so you can look out the buttonholes and then use a twisted wire hanger to give the illusion of a floating hat and glasses. Creepy and creative.

4. Chucky

This one might have been done to death, but the Chucky costume is a Halloween classic. After all, is there anything creepier than the idea of your dolls coming to life and trying to kill you? We didn't think so.

5. The Tethered

Another simple yet horrifying costume is that of The Tethered. These violent villains from horror film Us are meant to be doppelgangers, giving you an excuse to go as yourself – only scarier.

6. Slenderman

If you're on the tall side, Slenderman is the perfect costume for you. Not only is it creepy as hell, but it's also relatively simple to pull off. Just throw on your best suit, find a mask and get quietly lurking about the place.

7. Mummy

If you're looking for a creepy costume that's still a bit glam, give a Mummy costume a try. Pair a simple white outfit with head bandages that leave just enough room for some popping makeup. Add some creepy white contacts and you're good to go.

8. Dead little girl

Every Halloween brings out a whole heap of dead girls carrying a blood-stained teddy around. Why? Because it is scary as all hell and it just works. Plus, it's super affordable – just buy a cheap dress and trash it with fake blood.

9. Demon

If you're really out to scare this Halloween, embrace your inner demon. This look really doesn't require anything creative in the costume department, but you will need some great makeup effects and contact lenses. Simple, yet terrifying.

10. Zombie nurse

Is it really Halloween without a good old fashioned zombie costume? Recycle your nurse costume from years past and give it a twist with this zombie nurse look that will scare the pants off your bestie.
