Kids Halloween Costumes

Halloween in Australia has gained more popularity year on year and you can bet trick-or-treating is going to be bigger and bloodier than ever so you better start your costume planning now. This year's Halloween 2026 parties are sure to brew up some wicked storms so make sure your whole family has the opportunity to be involved. Find all Halloween costumes for kids all in one place at CostumeBox ready for you and your kid's Halloween 2026 celebrations.

Halloween costumes for kids can be cute, adorable or just plain scary. It all depends on the age of your child and to some degree, what they want to wear. As we all can appreciate, it's so much easier to dress little kids and toddlers in animal costumes, for example, whilst tweens or teens will have their own ideas about what they will and won't wear.

So if you are searching for some cute and cuddly or gruesomely fabulous costumes for kids this Halloween, let's take a peek inside CostumeBox's vault.

We have so many gorgeous costumes for girls, it's difficult to know where to start. We have princess costumes, witches costumes, clowns, devils, ghouls and zombies. If you want scary Halloween costumes for girls, we've got them in spades. So let's open our graveyard crypts and check out all the horrifying, gross, spine-chilling and even really cute and adorable costumes for girls in our vaults.

  • Pretty Batgirl costume: Has your daughter ever wanted to be Batgirl? Now's her chance. We have a lovely black and purple batgirl costume with gold details, cute tutu skirt, puffy batwings on the shoulders and even adorable bat ears. This is one of the all-time classic Halloween costume ideas for kids. You can't get better than Batgirl on All Hallows Eve.
  • Voodoo doll costume: With a little voodoo makeup, your little girl is going to make the perfect voodoo doll for Halloween. This is a delightful dress in pretty autumn patchwork colours, short puffy sleeves and a zigzag hem.
