PRODUCT DETAILS
What's in the Box
- Digitally printed tunic top with fibre-filled muscle chest and long sleeves
- Matching pants with attached foam-backed boot covers
This Kids Ikaris Costume brings Marvel's cosmic warrior from Eternals straight to your child's next dress-up day. The full bodysuit features digitally printed armor patterns in deep metallic blue with gold accents, a raised chest emblem, and padded muscle definition that makes any kid feel superhero-strong.
The wet-look fabric has a satisfying sheen, and the cosmic patterns printed across the tunic and pants capture the Celestial technology aesthetic from the film. Muscle padding sewn into the chest and arms gives the suit a heroic silhouette, while the high neck collar and attached boot covers complete the head-to-toe transformation. Foam backing behind the knees and boot areas adds structure without restricting movement — your child can run, jump, and strike superhero poses comfortably.
Perfect For
Book Week & School Character Parades: A standout pick for Marvel fans celebrating superheroes in literature, graphic novel days, or any "dress as your favourite hero" event at school.
Superhero Birthday Parties & Halloween: The muscled silhouette and cosmic armor make this a hit at Marvel-themed birthdays, trick-or-treating, or any costume party where your child wants to arrive as one of the Eternals.
Comic Conventions & MCU Fan Events: Perfect for young cosplayers attending Marvel meet-ups, superhero movie premieres, or family convention days where dressing as Ikaris is a conversation starter.
How to Wear It
Pair with dark sneakers or boots (shoes not included) and you're ready to go. The suit is designed to be worn over regular underwear — no additional layers needed unless the classroom is cold. Skip any accessories that clash with the cosmic armor print; the costume's built-in details do the heavy lifting.
Parent FAQs
What size should I order?
Check the size chart for chest and height measurements. The muscle padding runs true to size through the torso, so if your child is between sizes and growing fast, we'd suggest sizing up for longer wear.
Can they wear this over regular clothes?
The bodysuit is designed to be worn directly over underwear for the best fit. Adding layers underneath will bunch and hide the muscle definition — save the thermals for outdoor events only.
How do I wash this? Is the fabric durable?
Hand wash in cold water and hang to dry — the digitally printed details and foam backing don't love the washing machine. The wet-look polyester is surprisingly tough and resists tearing during active play.
Is this suitable for Book Week if our school focuses on books?
Absolutely — Marvel comics and graphic novels count as literature, and the Eternals storyline has deep roots in the Marvel comic universe. It's a natural fit for superhero or graphic novel Book Week themes.
Care: Hand wash cold, hang dry. Avoid machine wash to protect printed details.
