What Costume Goes With a Unicorn? Cute Pair Ideas
A rainbow is the classic costume to go with a unicorn: bright, easy, and it makes the unicorn look even more magical. Other cute answers to what costume goes with a unicorn are a cloud, a pegasus, a knight, a princess, a fairy, or for laughs, a "unicorn hunter" holding a net. All of them can be built from normal clothes, no fancy dress shop required.
If you're the unicorn and your friend is still on "I'll figure it out," The Costume Rack matches them to a partner costume from their vibe and closet, so you're not stuck guessing for them: Start my costume.

Rainbow, cloud and pegasus pairings
Rainbow and unicorn costume
The rainbow wears stripes of color: either one striped top, or each layer a different color (red tee, orange cardigan, yellow scarf). Colorful socks and a ribbon in rainbow order finish it.
Unicorn and cloud costume
Cloud costume: a white or grey hoodie with cotton wool or white pom-poms glued or pinned on. Add a raindrop or two made from blue paper. Super easy, super cute.
Pegasus costume
Basically a unicorn with wings and no horn. Wear white or pastel, add wings (cardboard or wire and tights), and you're the pegasus. Great for twins or best friends who want to match but not copy.
Fairy-tale partners: knight, princess, fairy
Unicorn and knight costume
- Knight: grey hoodie or sweatshirt, a cardboard shield with a crest, a sword made from cardboard and foil, boots.
- Why it works: the knight rides the unicorn. Do a piggyback photo. You will.
Unicorn and princess
A dress, a crown, maybe some pearls. Easy, classic, and great for a unicorn halloween costume girl duo with a sister or best friend.
Unicorn and fairy costume
The fairy and unicorn are both from the magical forest, so the colors can match: pastels, glitter, flowers. For more fairy partner ideas, see what costume goes with a fairy.
Funny pairings for friends
Want the group chat to laugh? Try these:
- Unicorn and unicorn hunter – safari hat, binoculars, a net, a clipboard. You "spot" the unicorn all night.
- Unicorn and pot of gold – a black top with gold coins (paper or chocolate) pinned on.
- Unicorn and "horse with a party hat" – your friend is the "budget unicorn" with a party hat on their forehead.
- Unicorn and glitter – one friend is literally just covered in glitter. "We're a package deal."
Mens cute unicorn costumes
Guys absolutely do unicorns, and it always lands. Pastel hoodie, a horn on a headband, a rainbow mane made from yarn or ribbons sewn or taped to a hood. Rainbow socks. Pair with a guy friend as the knight for a big laugh.
Picking a partner costume for someone else is pure guesswork: what's in their closet, whether they'll wear a horn, if they're cool with glitter. The Costume Rack asks each person about their vibe, closet and face paint, then matches them, and your shared rail shows everyone's pick in one place. Start my costume

How to make a unicorn costume
- Base: white, pastel or pink hoodie and leggings or jeans. A unicorn with a dress works too: any pastel or white dress.
- Mane: cut ribbon or yarn in rainbow colors and tape or safety-pin it down the hood, or braid colored ribbon into your hair.
- Ears: two small triangles of white felt or card on a headband.
- Tail: a bundle of ribbon or yarn pinned to the back of your waistband.
- Horn: see below.
No-sew unicorn horn
- Roll a sheet of gold or white card into a tight cone and tape it.
- Wrap a ribbon or pipe cleaner around it in a spiral.
- Trim the bottom flat, cut two small tabs and fold them out.
- Tape the tabs to a headband, or clip the horn into your hair.
Total time: about ten minutes. If it flops, roll the cone tighter or stuff a little tissue inside so it stands up straight all night.
Unicorn outfits for girls and teens
- Pastel slip dress with a jacket
- Tulle skirt, white top, rainbow socks
- Shimmer on cheekbones, totally optional
Cheap fancy dress costumes: unicorn edition
Unicorn costume fancy dress doesn't need a onesie. Everything above uses clothes you probably already own plus card and ribbon. That's a cheap fancy dress costume (UK) or cheap costume (US) that still looks put together.
Group version: the whole magical herd
A unicorn group costume (or herd, technically) gives each friend one color:
| Unicorn | Color | Detail |
|---|---|---|
| Classic | White | Gold horn |
| Rainbow | Multicolor | Ribbon mane |
| Dark | Black | Silver horn |
| Pastel | Pink or lilac | Glitter |
| Galaxy | Navy | Star clips |
Add a knight, a rainbow and a cloud and it's a full fairy tale. If your group is split between cute and spooky, flip to what costume goes with a ghost for the low-effort spooky side.
Find your unicorn's partner in about two minutes
The Costume Rack asks your vibe (spooky, glam, funny or cosy), your closet and how you feel about face paint, then matches each friend to one of sixteen costumes, like fairy or angel, which pair beautifully with a unicorn. Every costume is split into pieces with a version from what you own, and you share one link so everyone claims their costume on your rail.
