How to put it together
- 1
Put on a neutral t-shirt and pants to wear comfortably underneath the robe.
- 2
Slip on the long blue wizard robe and tie the inner or outer sash to secure it.
- 3
Put on your dark boots or shoes, ensuring the hem of the robe sits just above the floor to avoid tripping.
- 4
Fit the elastic band of the white beard over your head, adjusting it so the mustache sits comfortably under your nose.
- 5
Place the pointed blue wizard hat on your head, adjusting it to sit securely above the beard line.
- 6
Grasp your wizard staff in one hand to complete the legendary sorcerer look.
Makeup & hair
No complex makeup is needed as the large white beard covers most of the face. If your natural hair is visible under the hat, spray it with temporary white hair color or tuck it completely inside the hat.
