How do I make a quick DIY Sharky costume?

Start with a blue or gray hoodie. Cut white felt triangles for teeth and glue them along the rim of the hood, add two black felt circles for eyes on top, and safety-pin a cardboard fin to the back.

Is a shark mascot costume comfortable to wear all night?

Yes, fleece onesies are very comfortable, but they can get warm. Wearing lightweight t-shirts underneath and choosing a costume with a face cutout keeps you ventilated.

What should I wear under an inflatable shark costume?

Wear light, moisture-wicking clothing. Inflatable costumes rely on a continuous fan that circulates air, but they can still get warm during active movement.

How to put it together

1
Put on a lightweight t-shirt and shorts to stay cool inside the plush costume.
2
Step into the shark jumpsuit or onesie and pull it up over your shoulders.
3
Zip up the front of the jumpsuit, ensuring the white belly panel is centered.
4
Pull the shark hood over your head, adjusting it so the felt teeth frame your face without blocking your vision.
5
Slip your hands into the fin-shaped hand covers or matching blue gloves.
6
Lace up your matching sneakers or slip on the plush shoe covers.
7
Give the dorsal fin on your back a quick adjustment to make sure it stands upright.

Makeup & hair

Keep your hair tied back or tucked completely inside the hood. Since your face is fully visible through the shark's mouth, you can add a touch of blue face paint on your cheeks or nose for extra festive flair.

Sharky for couples, groups, kids & more

couples: Pair up with a lifeguard, a surfer with a cardboard bite taken out of their board, or another shark to recreate the famous Left Shark meme.
group: Gather a crew to go as a full shiver of sharks, or coordinate a family-friendly Baby Shark group with different colored shark suits.
kids: A cozy, zippered shark sleep sack or plush hooded toddler tunic is adorable and keeps them warm on chilly nights.
Plus size: Look for oversized, loose-fitting fleece onesies or inflatable shark costumes which offer a highly adjustable and comfortable fit.
pet: A simple hook-and-loop shark fin harness or a soft hooded shark cape works perfectly for dogs and cats.

Tips

Onesies and mascot suits trap heat quickly, so wear breathable base layers like athletic wear underneath.
If your jumpsuit has closed hand covers, make sure they have slits or fold back so you can easily hold drinks or use your phone.
Keep the dorsal fin upright by stuffing it with a little extra tissue paper or bubble wrap if it sags.
Practice your best shark walk—wiggling your hips to make the tail and dorsal fin sway is always a crowd-pleaser.
