Want a Halloween costume that looks like you put in real effort? Go Viking or go mermaid. Faux fur, sequins and capes read big in photos, and you won't run into five copies of yourself at the party.
Below are seven sexy Viking and mermaid costume ideas for 2026, for women and men, with the accessories that finish each one. Everything listed is in stock right now. Exclusively at RaveFix.
1. The Classic Women's Viking Costume
If you only look at one Viking costume, make it the 4pc Viking Warrior. You get a black and silver corset top, a faux fur mini skirt, a fur-trimmed black cape and a horned headpiece. That's the whole look in one box.
Add the Faux Fur Viking Arm Cuffs and flat black boots so you can actually walk between parties.
2. A Lighter Viking Look for Dancing
The 3pc Medieval Viking Costume is a tan suede-look romper with a sheer cape, a harness and a fur helmet. It's less fabric than the warrior set, so it's the better pick for a packed club or a Halloween rave. At $89.99 it's also the easiest on your budget.
Stack a pair of Warrior Arm Cuffs on top. They're $10 and they make the outfit look armored. Braid your hair loosely to one side and you're done.
3. Northern Warrior for a Darker Edge
Prefer black and brown over beige? The 4pc Northern Warrior is a quilted mini dress with a front slit, velvet shorts underneath, a brown belt and a velvet cape. It feels more medieval battle than horned helmet, which some people honestly like better. It's also the one that holds up best in daylight photos.
The Faux Fur Leg Warmers with Strap Detail pull it together and keep your legs warm on a cold night out.
4. The Viking Babe Dress
The 3pc Victorious Viking Babe is a suede and faux fur dress with a belt and a headpiece. It's the most wearable option here because it's one piece, and you can sit down in it. Stock is low, so if this is your pick, don't wait.
Go with Black Faux Fur Leg Warmers over heeled boots.
5. The Sexy Mermaid Costume in Sequins
The 3pc Majestic Mermaid pairs a purple corset with a green and blue sequin skirt and an aqua organza fishtail. Under party lights it shimmers like scales. Size small is the one left in stock.
Top it with the Starfish Headpiece and a Shell Necklace. Glitter on the collarbones finishes it. Mermaid works best at indoor parties where you'll stand and mingle; long skirts and crowded dance floors don't always get along.
6. A Flirty Shell-Top Mermaid
For the classic shell-top look, the Mesmerizing Mermaid has a sequin shell bra with pearls and a scale-print flare skirt. It's a statement piece, and only a few are left in small.
If you need more sizes, the Starstruck Mermaid Costume is a green and silver sequin tube top with a double-layered skirt, available in small through large for $85. Wear it with silver heels and wet-look waves.
7. Viking Costumes for Men
Guys get the best capes this year. The Mens Valiant Viking Warrior comes with a harness and cape, a belt, a faux leather skirt and a sheer shirt, in sizes small to XL. For more skin, the Mens Viking Hunk is a fur-trimmed shoulder harness with a chain, trunks, a belt and a headpiece.
Pair either one with a Viking costume for women and you've got an easy couples costume that doesn't feel cheesy. Match the colors: the Valiant Warrior's brown and grey sits right next to the Medieval Viking romper, while the black Hunk set looks sharp beside the Northern Warrior.
Tips for Wearing a Viking or Mermaid Costume
- Faux fur sheds a little at first. Shake it out outside the night before.
- Sequins scratch. Put a thin layer of body lotion on your arms where the skirt or top rubs.
- Vikings can wear flats. Mermaids look best in a simple heel or sandal that disappears under the skirt.
- Keep makeup on theme: smoky eyes and a little face paint for Vikings, highlighter and teal or lilac shadow for mermaids.
- Order this week if you want it before Halloween weekend, since the small mermaid sizes won't last.
