How do you make a DIY kids shark costume?

Glue a triangle of grey felt to the back of a grey hoodie to act as the dorsal fin, then glue white felt triangles along the rim of the hood for teeth.

What should a child wear under an inflatable shark costume?

Lightweight, breathable clothing like a t-shirt and shorts, as the fan-inflated suits can get warm inside during active play.

Are shark costumes safe for toddlers?

Yes, look for soft, sleeveless tunics or rompers that leave their face completely unobstructed and don't drag on the ground to prevent tripping.

For toddlers, choose a sleeveless tunic or a soft step-in romper with a wide face opening for safety and comfort.

How to put it together

1
Choose the style of shark costume, such as a plush zip-up jumpsuit, a slip-on tunic, or a battery-operated inflatable suit.
2
Dress the child in a comfortable, breathable base layer like a t-shirt and leggings to prevent chafing.
3
Have the child step into the jumpsuit or slip the tunic over their head, ensuring their arms and legs move freely.
4
Secure any closures, such as zippers, Velcro tabs, or the battery pack if using an inflatable version.
5
Pull up the hood so the shark's face and felt teeth frame the child's face without blocking their vision.
6
Finish with comfortable, slip-resistant sneakers suitable for walking outdoors.

Makeup & hair

Keep makeup minimal or skip it entirely; a touch of blue or grey face paint on the cheeks or a painted-on shark nose is a fun, optional touch.
