PRODUCT DETAILS
What's in the Box
- Purple plush hooded onesie with front zipper
- Attached 3D unicorn hood with gold horn, ears & rainbow mane
- Attached rainbow tail
This Adult Unicorn Onesie Costume turns any costume party into a whimsical fantasy moment — purple plush body with a white front panel, rainbow faux fur mane cascading down the hood, and a shimmery gold fiber-filled horn standing tall. Full-zip front means easy on and off without wrestling the thing over your head.
Soft plush outer shell feels like wearing a blanket, with elastic cuffs at wrists and ankles to keep the fit snug and the warmth in. The 3D hood is where the magic happens: plush nose, upright ears, metallic gold spiral horn, and that rainbow gradient mane flowing from yellow through pink to blue. Attached rainbow tail at the back finishes the look.
Perfect For
Halloween & Costume Parties: Stand out at pub crawls, house parties, or trick-or-treating with mates — the full-body silhouette reads instantly as unicorn from across the room.
Conventions & Cosplay Events: A crowd favourite at comic cons, anime expos, or fantasy-themed meetups where comfort matters as much as the costume.
Themed Events & Casual Dress-Up: Perfect for rainbow parties, mythical creature nights, or just lounging at home when you want maximum cozy with maximum whimsy.
How to Wear It
Zip into the onesie over a t-shirt and leggings if the venue runs cold, or wear it solo if you're headed somewhere warm. Pull the hood up to show off the horn and mane — that's the hero moment. White sneakers or slippers complete the look without competing with the rainbow palette.
FAQs
Q: What size should I order?
Check the size chart image for waist measurements — this costume runs relaxed through the body. If you're between sizes or want a looser lounge-around fit, size up.
Q: Can I wear this over regular clothes?
Yes — the full-zip front and roomy cut mean you can layer a tee and leggings underneath. Handy if the party's outdoors or you're headed to a chilly convention hall.
Q: How do I wash this? Is the plush durable?
Spot clean or gentle hand wash in cold water, then air dry flat. The plush holds up well to light wear; avoid machine washing the horn and mane sections to keep their shape.
Q: Is this suitable for conventions where I'll be walking around all day?
Absolutely — the elastic cuffs and full-zip design make it easy to adjust for comfort. Breathable enough for indoor venues, warm enough for evening outdoor events.
Care: Spot clean or gentle hand wash cold, air dry flat.
