The best Halloween costumes for kids: fairies, witches and a touch of magic

Halloween is just around the corner, and with it comes one of the most anticipated nights for the little ones in the house. A magical evening where dreams, fashion, and fantasy blend to create the best Halloween costumes for children.

Did you know that this tradition is more than 2,000 years old? Its origins date back to the Celtic ritual of Samhain, which marked the end of summer and the beginning of a new season. Today, this ancient celebration has transformed into a party where anything is possible: witches, fairies, unicorns, and stars fill the streets and homes with lights, candy, and trick-or-treating.

Halloween is no longer just a night of scares; it's a catwalk of children's imagination. And this year, the question is inevitable: is your little one more of a charming witch, a luminous skeleton, or a luminous fairy? Whatever your style, here you'll find inspiration to create one of the best Halloween costumes for girls and boys, full of details, color and magic.

What are the trendiest children’s Halloween costumes for 2026?

The trendiest children’s costumes for 2026 are less about fancy dress and more about everyday wardrobe staples. This Halloween, the trend is to mix and match everyday clothes with a single detail that makes all the difference. Here are the season’s key trends:

Piece-by-piece looks: a cape, a hat or a tulle skirt are all it takes to turn any outfit into a character.

Outfits that last more than one night: like the skeleton pyjamas, which go straight from the party to bed without a hitch.

Minimalist accessories: a headband with a tiny witch’s hat proves that, sometimes, less is more.

Stylish classics: skeletons, witches and bats in black, with silver details that sparkle in the glow of the jack-o’-lanterns.

Simple ideas so every little one can create their own character and enjoy Halloween in their own way.

Skeleton fancy dress: the cutest look for Halloween night

There are children who look forward to Halloween all year round. They count down the days, practise their best scary faces and dream of going out to trick-or-treat as soon as night falls. For them, a Halloween costume for boys has to be fun, easy to wear and, above all, comfortable so they can keep on the go without stopping for a minute.

This outfit ticks all the boxes: black pyjamas with a skeleton print and a matching skull hat. Nothing more, and nothing less, to become the friendliest skeleton in the neighbourhood.

The key to making it work lies in its simplicity. Pair it with his favourite trainers for roaming the streets and doorways, and add a pumpkin basket to collect the spoils. And the best bit comes when he gets home: as they’re pyjamas, he can go straight to bed without taking them off, dreaming of ghosts, bats and mountains of sweets.

A costume that’s not too scary but sure to win hearts. Because on Halloween, it’s the littlest skeletons who shine the brightest.

Stylish little witches

Abracadabra. A cloud of stars, a twist of a cape, and out pops a three-foot-tall witch with a basket ready to be filled with candy. If your little one dreams of casting spells tonight, here's one of the most magical Halloween costumes for girls.

This look is achieved with two pieces: a black cape and a black peaked hat with silver stars. Easy to put on, comfortable for running, and ready for adventure.

To add an even more mysterious touch, combine it with a broom, a wand, or a plush black cat as a faithful companion. An extra idea? A matching coven with sisters, cousins, or friends to form the most fun group of witches in the neighborhood.

Because Halloween is pure magic, and experiencing it dressed as a witch makes it even more special.
