Step into the body harness system, pulling the thigh straps up first, then securing the waist belt and shoulder straps.
- 3
Pull on the knee-high brown boots over the white pants, ensuring the pants are tucked in smoothly.
- 4
Put on the cropped camel-brown Scout Regiment jacket over the harness.
- 5
Drape the green hooded cloak over your shoulders and fasten it at the neck.

Makeup & hair
Eren has medium-length, messy dark brown hair that falls just past his ears, sometimes styled in a half-up bun in later seasons. Keep makeup minimal and natural, focusing on defined, intense eyebrows to capture his signature fierce expression.
