Adjust the tunic so the printed scales face forward and the tail drapes naturally behind your legs.

Position the bass headpiece or hood over your head, ensuring your face is visible through the open mouth.
- 5
Attach the lightweight plastic fish hook or fake lure to the side of the headpiece for a funny 'just caught' effect.

Tips
- Wear lightweight layers underneath the tunic, as stuffed polyester costumes can get warm quickly.
- If the tunic arrives creased, hang it up or use a garment steamer on low heat to smooth out the fins.
- Practice walking in the tunic beforehand, as some fish tails can restrict your stride slightly.
- For photos, strike a stiff, horizontal pose like a prize catch being held up by a fisherman.
