How to put it together
- 1
Put on the brown long-sleeve shirt and brown pants to create your base 'fur' layer.
- 2
Layer the snug yellow t-shirt over the brown long-sleeve shirt, pulling it up slightly to mimic Gus's too-small shirt look.
- 3
Attach the brown mouse tail to the back waistband of your brown pants using a safety pin.
- 4
Place the royal blue beanie on your head, ensuring the attached DIY felt mouse ears sit prominently on the sides.
- 5
Use pink face paint to draw a small, round pink circle on the tip of your nose.
- 6

Makeup & hair
Keep hair tucked completely under the blue beanie. Paint the tip of your nose with bright pink face paint, and optionally draw a few simple black whiskers on each cheek using an eyeliner pencil.
