PRODUCT DETAILS
What's in the Box
- Digitally printed blue jumpsuit with leopard spots, tiger stripes, and cat paw sleeve cuffs
- Detachable fibre-filled tail with wire for curled shape
- Derpy Tiger character face mask with eye holes and hook-and-loop strap
This Kids Derpy Tiger Costume brings the lovable, clumsy supernatural feline from K-Pop Demon Hunters to life, with a vibrant blue jumpsuit that's covered in leopard spots and tiger stripes. The character mask captures Derpy Tiger's friendly face, and the detachable tail holds its curled shape thanks to a wire core.
Bright blue dominates the jumpsuit with gradient shading from darker blue at the limbs to lighter blue on the torso. Leopard spot pattern splashes across the chest, while dark blue tiger stripes mark the sides, back, and limbs. The sleeve cuffs are printed with cat paw pad designs. The mask has cut-out eye holes for clear vision and secures with a hook-and-loop strap at the back.
Perfect For
Book Week & Character Days: A standout pick for K-Pop Demon Hunters fans celebrating Book Week or animated film character parades at school.
Halloween & Costume Parties: Pairs with other K-Pop Demon Hunters characters (Rumi, Mira, Zoey) for a group costume theme, or goes solo as the supernatural protector of the gang.
Themed Dress-Up Play: Great for kids who want to re-enact scenes from the Netflix film, perform the hit song "Golden", or just dress up as their favourite clumsy feline guardian.
How to Wear It
Slip the jumpsuit on over regular clothes, secure the mask at the back with the hook-and-loop strap, and attach the tail. Shoes not included — pair with blue or white sneakers to match Derpy Tiger's look. The mask sits comfortably over the face with eye holes for visibility.
Parent FAQs
Q: What size should I order for my child?
Sizes run S (4 years), M (5-6 years), L (7-8 years), XL (9-10 years). Check the size chart for chest and height measurements. If your child is between sizes or growing fast, size up for longer wear.
Q: Can they wear this over their school uniform?
Yes — the jumpsuit is roomy enough to go over a t-shirt and leggings or shorts. The mask sits over the face without pressing on the nose, so it's comfortable for a full school day or party.
Q: Will this work for a K-Pop Demon Hunters group costume?
Absolutely. Derpy Tiger is the supernatural protector of the K-Pop Demon Hunters gang, so your child can team up with friends dressed as Rumi, Mira, or Zoey for a coordinated Halloween or Book Week group.
Q: Is the tail detachable for washing or storage?
Yes — the tail attaches and removes easily, which makes the costume easier to pack and store after the event. The wire inside the tail holds its curled shape even after detaching.
