Imposter Costumes

Few costumes generate more instant recognition among primary-school kids than the space crewmate silhouette — the rounded bean-shaped spacesuit with the coloured visor. Whether your child wants to be the innocent crew member or the suspected imposter among their classmates, the space crewmate costume is a crowd-pleaser that photographs brilliantly and works for all ages and genders.

Our range includes classic space crewmate jumpsuits in multiple colours, fully inflatable bean-shaped costume suits with fans, and accessories to complete the look. All costumes ship from our Melbourne warehouse with standard and express options available.

Space Crewmate Costume Styles in Our Range

Classic Crewmate Jumpsuit — form-fitting space suit in signature crewmate colours (red, blue, and more) with the iconic helmet hood. Comfortable for a full school day, easy to recognise from across the parade ground.
Inflatable Bean-Shape Costume — the fully inflatable round crewmate suit with built-in fan, worn like a wearable bubble. One of the most show-stopping costumes at any parade — kids love the wobbly walk and the instant recognition.
Crewmate Backpack Style — jumpsuit with a built-in backpack detail to capture the complete character look, without the bulk of the inflatable version.

Tips for Choosing an Imposter / Crewmate Costume for Book Week

Link it to a book. The gaming-character costume works best at Book Week when tied to a published book. Look for official game tie-in books, graphic novel adaptations, or related chapter books your child can reference if asked by a teacher.
Colour matters. The classic colours — red and blue — are the most immediately recognisable. Red in particular is associated with the imposter character and gets the biggest crowd reaction.
Inflatable vs jumpsuit. The inflatable suit is the show-stopper but can be warm and a little cumbersome for a full school day. The jumpsuit version is more practical for parade and classroom. Both look great in photos.
Works for all ages. The crewmate costume suits prep through upper primary and beyond — it's one of the rare costumes that looks equally good on a 5-year-old and a 12-year-old.

Frequently Asked Questions — Imposter & Space Crewmate Costumes

Is this costume suitable for Book Week?

Yes, with a little preparation. Book Week costumes need to be tied to a published book — look for official game tie-in books, graphic novel adaptations, or related space adventure stories your child can name if asked. The costume itself is colourful, distinctive, and universally recognised by primary-school kids and teachers.

What age group does this costume suit?

The space crewmate costume suits children from prep through upper primary. The jumpsuit style is available in kids' sizes across a wide range; the inflatable version is best suited to children aged 6 and over who can manage the built-in fan and slightly bulkier fit.

Which colour is most popular?

Red is the most popular choice — it's the iconic imposter colour and gets the biggest reaction from classmates. Light blue is the second most popular. Both look great in parade photos and are immediately recognisable.
