When is Halloween 2026?

Halloween falls on Saturday 31 October 2026. Trick-or-treating, school dress-up days and Halloween parties all happen around this date, so it pays to sort costumes out by mid-to-late October — popular styles and sizes sell out fastest in the final week.

Most Popular Kids Halloween Costumes

Some Halloween looks are favourites year after year. Here are the styles Australian kids reach for most:

• Witches & wizards — classic, comfortable and easy to wear, with hats and capes that work for the whole night.
• Vampires & Dracula — a cape and medallion instantly transform any outfit into a spooky classic.
• Skeletons & ghosts — glow-in-the-dark and printed jumpsuits are perfect for trick or treat after dark.
• Scary clowns & monsters — for older kids who want a fright-factor look.
• Superheroes — a year-round favourite that doubles for Halloween. Browse Superhero Costumes.
• Animals & creatures — soft onesies that are great for younger children. See Animal Costumes.

Choosing a Kids Halloween Costume by Age

Toddlers & babies: keep it soft and simple — animal onesies, little pumpkins and friendly monsters are easy to get on and off and comfortable for small children.

Primary-school kids: this is the sweet spot for witches, superheroes, skeletons and characters — fun, recognisable and not too scary for school dress-up days.

Tweens: older kids often want a bigger fright factor — scary clowns, deluxe vampires and detailed hero suits deliver more impact.

Scary vs Fun: Pick the Right Vibe

Not every Halloween costume needs to be frightening. For school events and younger kids, Funny Costumes and Character Costumes keep things light. For trick or treat and parties, spooky witches, vampires and skeletons set the mood. Finish any look with Masks and Props.
