Frequently Asked Questions About Kids Costumes

Find answers to common questions about choosing sizes, delivery, returns, Click & Collect and shopping for children's costumes.

What size costume should I choose for my child?

Costume sizing can vary between brands, so we recommend checking the measurements shown in the size guide on each product page. Compare your child's height, chest, waist and clothing size with the supplied measurements.

When your child falls between two sizes, choosing the larger size will usually provide more comfort and room for clothing underneath.

How long does delivery take?

We offer Australia-wide delivery through Australia Post. Standard delivery generally takes approximately 2–10 business days, while Express Post generally takes approximately 2–4 business days.

Delivery times are estimates and may vary depending on your location, seasonal demand and Australia Post conditions.
