Step into the Underworld with this sultry Malaria costume guide. She is the ultimate femme fatale from The Grim Adventures of Billy and Mandy.

This look requires elegance, confidence, and plenty of black velvet. Let’s break down how to recreate her vintage noir style.
Complete Costume Breakdown
Clothing & Core Pieces
The dress is the absolute centerpiece of this outfit. Malaria wears a floor-length black gown that hugs her silhouette perfectly.
Look for a sweetheart neckline to match her animated design. This cut highlights the décolletage and stays true to the character.
We have selected two fantastic dress options for you. One features a daring slit which makes walking much easier.
The second option is a mermaid style that emphasizes curves. Choose the one that makes you feel most powerful.
You cannot become Malaria without her signature gloves. She wears classic black opera gloves that reach past the elbow.
Velvet or satin gloves work best here. They add an instant touch of vintage Hollywood glamour to the ensemble.
Accessories & Details
Her hair defines her noir aesthetic completely. You need a short, black flapper-style wig with a finger wave look.
A simple black choker sits at her neck. It breaks up the silhouette between the dress and her pale skin.
Her accessory of choice is a distinct parasol. You need a black umbrella with a striking red interior lining.
This prop is essential for dynamic posing. It gives you something to hold and adds a splash of color.
Cosplay Tips
Malaria is known for her pale grey skin. You will need high-quality grey body paint for your face, neck, and arms.
Be sure to seal the body paint thoroughly. You do not want to stain your beautiful black velvet dress.
For makeup, focus heavily on the eyes. Use deep purple eyeshadow to create a dramatic, sunken eye look.
Finish the face with a dark red lipstick. A matte formula stays on longer and looks more period-accurate.
Character Vibe & Styling Notes
Malaria moves like she is underwater. Keep your movements slow, fluid, and incredibly deliberate while in character.
She is never in a rush. Channel the energy of a 1920s film star who knows everyone is watching her.
When posing, use the umbrella to frame your face. Tilt your head slightly and keep your eyes half-lidded.
Final Thoughts
This costume is perfect for fans of classic cartoons and gothic fashion. It is elegant, recognizable, and very fun to wear.
Get ready to charm the Grim Reaper himself. Enjoy bringing this iconic Underworld beauty to life.
