How to put it together
- 1
Put on lightweight, breathable base layers like a t-shirt and shorts to stay cool inside the plush suit.
- 2
Step into the legs of the blue shark jumpsuit and pull it up over your shoulders.
- 3
Slip your hands into the flipper sleeves, ensuring you can still use your hands if the suit has wrist slits.
- 4
Pull the shark hood over your head, positioning your face clearly in the open mouth cutout.
- 5
Zip up the front or back closure of the jumpsuit securely.
- 6
Lace up your white canvas sneakers to complete the look.
Makeup & hair
Keep your hair tied back or flattened under a wig cap so it stays securely inside the hood. No makeup is required, but you can apply blue face paint around your eyes for an extra touch of color.
