How to put it together
- 1
Put on the dark brown or black full-body morphsuit as your base layer.
- 2
If using a plain suit, use fabric paint to sketch out a ribcage and skeletal muscle lines in dark red and black.
- 3
Secure the siren headpiece to your head, ensuring the central pole aligns with your neck and the two sirens point outward.
- 4
Wrap loose black wires or yarn around your neck and the base of the sirens to mimic the creature's organic, mechanical look.
- 5
Put on the elongated claw gloves, pulling the sleeves of the bodysuit over the cuffs for a seamless look.
- 6
Wear dark, low-profile shoes or boots that match the color of your bodysuit.
Makeup & hair
Since this costume utilizes a full-face mask or morphsuit hood, no makeup or hair styling is required. If your face is exposed beneath the headpiece, apply black face paint around your eyes and mouth to blend into the shadows.
