10 Best Halloween Costumes for Kids UK 2023

It may look like just a jumpsuit, but this costume comes with a whole lot of snazzy extras. It's complete with wings and ears, which are attached to the costume - so not only will your child look the part, they also aren't going to lose any parts either!

We love that this outfit is machine washable, making cleaning the costume after use much easier. As well as being suitable for all genders and a wide range of ages, it provides the perfect balance between cute and scary. That's why it's our top pick!

This costume wouldn't be out of place sailing on the seven seas, and it's sure to be a hit with your youngster if they love pirates. The velcro trousers and t-shirt make this an easy costume to throw on, and it's a comfy option too.

With a plastic cutlass, an eyepatch and a hat, your little one will have all the accessories to really look the part! With hundreds of positive reviews on Amazon, this one will surely be a hit with both you and your child!

This dress and hat combination makes for a classic Halloween outfit that looks super chic. The purple details on the dress add a pop of colour to the mostly black costume, and kids will love prancing around in the flared sleeves and cobweb-adorned hat. 

Unlike some of the other outfits on our list, this one comes with everything you could possibly need - so there's no need to fork out on extra accessories later down the line. Let your child cast a spell on their friends with this wonderfully witchy costume!

Dragons probably aren't your first thought when it comes to Halloween costumes, but when you see this sweet and cosy little onesie, we reckon you won't be able to resist dressing your toddler up as one!

The toothy hood is a simple way to keep your kid warm on a cold autumn evening when they're out trick or treating. The soft material is gentle on their skin, and they can have lots of fun playing with the sewn-on tail too! 

This adorable little costume is the perfect way for toddlers to get in the Halloween spirit. Available in four different sizes, it'll fit kids ranging from the age of a few months to 3 years. The tiny hat and shoes make this one of the cutest Halloween looks we've ever seen!

Although the hat and shoes make the outfit look complete, you might struggle to keep these accessories on your toddler's feet and head. They'll be wonderful for photos at the start of the night before your little one decides to kick them off! 

Darth Vader is one of the most famous villains in film history, so this product is a must-buy for Star Wars fans! Kids will love dressing up in the full regalia, with the mask, belt and cape all included. 

The mask is soft and easy to fasten, so even young children will feel comfortable wearing it. This costume is only suitable for sponge washing, though, so if your little one does manage to spill party food and drink down it, then stains will be difficult to remove.

During the daytime, the colourful skeleton on this costume stands out, but it's in the dark that this costume really comes to life. Or not... it is a skeleton after all! We love the way the ribcage glows like an X-ray, adding a fun dimension to this onesie.

The sizing options of this costume are a bit limited, so it'll only work for kids between the ages of 4 and 12. It also doesn't come with any exciting extra accessories which is a shame. 

If you think it might be tricky getting your little one into an outfit with lots of parts, this costume will do the trick - or treat! The simple poncho style means you can just put it on your baby or toddler over their other clothes, making the process of dressing up a whole lot less of a faff for you. 

The main downside to this costume is the light colour - this means it won't be safe from spillages and is likely to stain easily! The little hat tops off the entire outfit nicely too!

If your child wants minimum fuss but maximum impact, then a morph suit is a great way to go! It's an all-in-one costume that covers you from head to toe, ensuring your kid will be able to shock all their friends with their unrecognisable appearance. The Zalgo design, based on a horror character from internet comics, is incredibly creepy!

The fantastic thing about these suits is that they come in a wide range of shapes and sizes, and their stretchiness will allow for quite a lot of leeway within each size. They're definitely expensive if only worn once, though!

This costume has the advantage of being all-in-one, with the shirt and cape sewn together. This makes it easier to put on and less likely to lose components. The red and black colours create a gloriously gothic look that will look amazing paired with some dark makeup!

Disappointingly, this costume doesn't come with the trousers or the cane you see in the picture, so you'll have to buy them separately - this is a shame as it's already quite an expensive outfit.
