Killer Bunny Costume
Transform a cute holiday mascot into a spine-chilling Halloween nightmare.
The Killer Bunny is a classic horror archetype that subverts the friendly Easter mascot into a terrifying slasher villain. Perfect for horror fans who want a high-impact, creepy look, this costume relies on a contrast between innocent bunny features and gory details. The signature look combines a realistic or plush rabbit mask with fake blood, distressed clothing, and a menacing prop weapon.

How to put it together
- 1
Put on the red and black plaid flannel shirt as your base layer.
- 2
Step into the denim overalls, adjusting the shoulder straps so they sit comfortably.
- 3
Use sand paper or scissors to fray the edges of the shirt cuffs and overall hems for a worn-out slasher look.
- 4
Apply fake blood or red fabric paint to the front of the overalls and the white plush gloves, letting it dry completely.
- 5
Put on the white plush gloves.
- 6
Place the creepy bunny mask over your head, ensuring the eye holes align correctly for visibility.
- 7
Equip your prop weapon of choice to complete the sinister silhouette.
Makeup & hair
Since this costume features a full-head mask, hair and makeup are optional. If your mask has open eye holes, apply dark black eyeshadow or face paint around your eyes to blend your skin into the mask's shadows.
Killer Bunny for couples, groups, kids & more
- couples
- Pair up as a Killer Bunny and a terrified victim in pajamas, or go as a dual 'Bad Bunnies' duo.
- group
- Form a pack of creepy forest animals, including a killer bear, a sinister deer, and an evil fox.
- kids
- Use a less intense, slightly goofy bunny mask with glowing EL wire instead of heavy gore.

Tips
- Ensure your mask has adequate ventilation and visibility, especially if you plan to wear it outdoors at night.
- Use fabric paint instead of real fake blood on your clothes so the stains dry permanently and won't rub off on furniture.
- Keep a spare pair of normal shoes on hand; dirty sneakers or work boots complete the look perfectly.
- If using a mask with LED lights, carry spare AA batteries in your overall pockets.
