- 1
Put on your brown pants or leggings to serve as the base chipmunk fur.

- 3
Attach the brown plush tail to the back of your pants or the lower hem of the hoodie using a safety pin.
- 4
Place the chipmunk ears headband securely on your head, positioning it just behind your hairline.
- 5
Put on the round black-framed glasses, pushing them slightly up the bridge of your nose.
- 6
