Unicorn Halloween Costume Ideas, From Party to Rave

By Zoey Unicorn · 5 min read

Okay, you knew we were going to do this one. A unicorn Halloween costume is basically our love language. It is bright, it photographs like a dream, and it is the rare costume you can wear again at the next rave, festival or pride party.

Here is the formula. Every unicorn look needs a horn, a pastel or holographic base, something sparkly and white fishnets. Keep the horn and the fishnets the same, swap the base, and you get a totally different unicorn every time. Below are seven looks, piece by piece, so you can shop one in a single go.

Rainbow unicorn costume

This is the easiest unicorn on the list because the dress does everything. The Pastel Rainbow Mesh Flow Dress is sheer ombre mesh in pink, lavender, blue, green and yellow, with a criss-cross halter, off-shoulder bell sleeves and a handkerchief hem. Add Holographic Bubblegum Pink Heart Pasties under the mesh, White Diamond Net Tights and gold heels. Done.

Sexy unicorn bodysuit costume

Soft, shiny and a little bit sweet. The Baby Pink Metallic Ballerina Bodysuit is pink metallic shimmer with criss-cross halter straps and a chiffon ruffle at the hip, so it reads unicorn and ballerina at once. Pair it with the same white diamond net tights and pink glitter platform boots.

Pink unicorn costume

For the full pink fantasy, start with the Metallic Pink Bow Triangle Bikini Top and add the Metallic Pink Bow High-Waist Garter Bottom, which has satin bows at the hips and built-in garter straps. Clip on White Fence Net Thigh Highs and you have a costume that doubles as a rave set.

Unicorn bra and skirt outfit

The cutest, cheapest unicorn here. This unicorn bra set has rainbow-mane unicorns on each cup and a matching panty. Layer the Baby Pink Sheer Mesh Skater Mini Skirt over the top and finish with white fishnet thigh highs. Space buns under the horn take it all the way.

Unicorn rave outfit

Go full rainbow. The Rainbow Carnival Beaded Jewel Bra with Pearl Clouds is the statement piece, with beaded rainbow cups, pearl clouds and draped jewel chains. Pair it with the Rainbow Vinyl Cloud High-Waist Short, which brings rainbow stripes and a sequin cloud right at the front, plus white fishnet thigh highs. Add pink braids and as much face glitter as you can handle.

Unicorn corset costume

Want shape? The Unicorn Print Mesh Open-Cup Underbust Waist Cincher is lavender mesh printed all over with rainbow unicorns, stars and clouds, so it does the theming for you. Wear it over the Bubblegum Pink Hologram Ruffle Wrap Bra Top with Bubblegum Pink Holographic High-Waist Cheeky Shorts and fishnets.

Unicorn fairy costume with wings

Add wings and your unicorn becomes a pegacorn. The Baby Blue Sequin Butterfly 2PC Set is iridescent baby blue with long bell sleeves and a sequin butterfly skirt. Clip on the Iridescent Glitter Fairy Wings for color-shifting organza wings, then white fishnets and a pastel horn. Find more styles in our wings collection.

Want it in one buy?

If you would rather not build it, grab a set. The Twinkle Toes Unicorn 4-Piece Costume Set comes with a white halter crop with a rainbow heart, a rainbow tulle skirt, a tailed panty and a rainbow horn headband. For a sexier unicorn, the Unicorn Marvel Lingerie Set is sheer mesh with rainbow appliques, a garter belt and its own horn headband.

Finish the look

Every look above shares the same finishing touches: a flower crown unicorn horn, pastel eyeshadow, face gems and a lot of glitter. Moon Dust XL Glitter in Unicorn Skin is chunky iridescent glitter for your cheekbones and hairline, and you will find face jewels, body glitter and more in our glitter and face gems collection. Bobby pin the horn into your hair so it stays put all night.

Pasties are the easiest way to theme a sheer or low-cut look. Go sugary with Smarties Party Pastel Kandi Multicolor Glitter Heart Pasties, holographic with Care Bare Stare Holographic I Heart U Pasties, or full rainbow with Rainbow Glitter Cloud Pasties.

Then pick your legs. White fishnets are the classic, but White Sheer Backseam Thigh High Stockings look soft and vintage, Pink Stay Up Stockings keep it sheer and sweet, and Pink Thigh High Fishnets lean all the way into pink.

From Halloween party to rave

Every piece here keeps working after October. Drop the horn and wings, keep the holographic base and the glitter, and you are rave ready. Our rave lingerie guide has more ideas. If you want a classic duo instead, our devil and angel costume guide never misses.
