PRODUCT DETAILS
What's in the Box
- Digitally printed tunic top with emerald-green wet-look finish, silver foil chest emblem, mandarin collar, and attached flowing cape panels
- Matching full-length leggings with stirrup bottoms to secure under shoes
This Kids Sersi Costume brings the mystical power of Marvel's Eternals right into your Book Week lineup. The emerald-green tunic features concentric armor patterns printed across the chest, silver foil accents on the shoulders, and a high mandarin collar that says "immortal celestial being" without saying a word.
The wet-look stretch fabric catches the light like ancient mystical armor. Flowing cape panels in green-to-white ombre attach at the shoulders, and the fitted leggings have elastic stirrups that tuck neatly under shoes. The glittery silver emblem at the chest is the final touch — unmistakably Sersi.
Perfect For
Book Week & Superhero Parades: A natural pick for Marvel-themed Book Week days, superhero dress-up events, or any classroom character parade where comic-book heroes rule.
Movie Character Days & Halloween: Perfect for Marvel Eternals fans, Halloween trick-or-treating, or superhero-themed birthday parties where your child wants to stand out as the celestial protector.
Comic Conventions & Cosplay Events: Ideal for kids' comic con panels, family cosplay meetups, or movie premiere events where Marvel fans gather.
How to Wear It
Pair with comfortable sneakers or black boots (stirrups tuck under either). Let the cape panels flow freely — no need for extra accessories; the costume's built-in details do the work. Hair down or in loose waves matches Sersi's on-screen look.
Parent FAQs
What size should I order?
Check the size chart for chest and height measurements. The wet-look fabric has stretch, so if your child is between sizes we'd suggest sizing up for longer wear and easier movement.
Can she wear this over regular clothes for indoor play?
The tunic and leggings are designed to be worn as the outfit itself — thin enough for indoor classroom use, warm enough for outdoor trick-or-treating. Layer a long-sleeve top underneath if it's cold.
How do I wash this? Is the fabric durable?
Hand wash in cold water or gentle machine cycle inside-out to protect the foil accents. Hang dry — the wet-look finish stays glossy if you avoid high heat. The stirrups are elastic and hold up well to repeated wear.
Are shoes included, or do we need to supply those?
Shoes are not included. The stirrups work with any sneakers or boots your child already owns — just tuck the elastic loop under the sole and the pants stay in place all day.
Care: Hand wash cold, hang dry, no ironing on foil areas.
