PRODUCT DETAILS
What's in the Box
- Padded muscle top with six-pack abs, pecs, and bicep padding
- Long sleeves with elastic cuffs
- Crew-neck pullover design
This Kids Muscle Costume Top turns any Book Week hero into a comic-book powerhouse — padded six-pack abs, defined pecs, and bulging biceps all built into a lightweight pullover. Slip it on over regular clothes and you've got instant superhero strength.
The tan fabric mimics skin tone, so it works under capes, vests, or open shirts — or wear it solo for a bodybuilder look. Foam padding holds the muscle shape without weighing your kid down, and elastic cuffs keep the sleeves in place during playground rescues.
Perfect For
Book Week & Superhero Dress-Up Days: A natural base layer for any comic-book hero — pair with a cape and mask for a Captain Underpants-style look, or wear under a vest for a strongman storybook character.
100 Days of School & Kindy Costume Parades: Works for "Strongest Kid in School" themes, gym teacher dress-up, or any costume that needs muscles. Easy to pull on over school uniform if you're running late.
Halloween & Costume Parties: Team it with black pants and a belt for a generic superhero, or add wrestling boots and a championship belt for a WWE-style costume. The muscle padding does the heavy lifting.
How to Wear It
Pair with black shorts or pants (not included) and any superhero accessories — cape, mask, gloves, belt. For a full strongman look, add a fake moustache and slick the hair back with gel.
Parent FAQs
What size should I order?
Check the size chart image on this listing — it's based on chest measurement and height. The padding adds bulk, so if your kid is between sizes we'd say stick with their usual size rather than sizing up.
Can they wear this over regular clothes?
Yes — it's designed to go over a t-shirt or long-sleeve top. The crew neck sits comfortably and the elastic cuffs keep it from riding up.
Is the padding durable? Will it flatten after a day of wear?
The foam padding bounces back after wear. Spot-clean only to keep the shape intact — don't machine wash or the padding may shift.
Do we need to buy pants separately?
Yes — the top is sold on its own. Black trackies, shorts, or leggings work perfectly and you probably already have them at home.
Care: Spot-clean only. Do not machine wash or tumble dry.
