Spy Costumes for Kids — Secret Agents for Book Week

Spy costumes tick every box for a successful Book Week parade — they're cool, clever, and tied to a rich genre of children's books. From classic secret agents in black to high-tech gadget-carrying operatives and undercover investigators, the spy genre covers picture books, junior chapter books, and middle-grade adventure series that Aussie kids love. A spy costume rewards a child who knows their character and can hold the mysterious air to match.

Our spy costume range includes FBI tactical sets, disguise accessory kits, agent vest and helmet combos, and the props that complete the spy look. Whether your child wants to be a field operative, an undercover agent, or a tech-equipped junior spy, you'll find it here. All costumes ship from our Melbourne warehouse.

Spy Costume Styles in Our Range

FBI / Tactical Agent Sets — SWAT-style vest, helmet, and badge combos for the modern operative look. Great for tech-spy and government-agent character costumes.
Disguise Accessories — hats, glasses, and prop kits for building an undercover agent look from everyday clothes. Sometimes the best spy is the one no one suspects.
Prop & Gadget Accessories — toy handcuffs, shoulder holsters, and agent prop kits for the finishing details that sell the character.
Undercover Operative Costumes — dark, sleek costume sets for the classic movie-spy silhouette.

Tips for Choosing a Spy Costume for Book Week

Know your book. The spy genre is rich in Book Week tie-ins — Alex Rider, Spy School, I, Q, Junior Agent series, The Medusa Project, and dozens of picture-book spies and secret agents. Make sure your child can name the book when the teacher asks.
All-black is your friend. A spy costume built on a black base (black shirt, black trousers) plus a vest or tactical accessory reads "secret agent" immediately. Add a prop earpiece or toy handcuffs and the look is complete.
Gadgets complete the character. The right prop — a toy communicator, holster, or badge — does more for a spy costume than any full-costume set. Browse our Props & Accessories range for finishing pieces.
