Materials for Baby Shark Costume

Basic Supplies
You can make a fun baby shark costume with just a few basic items. Here’s what you’ll need for most diy projects:
-
Hoodie or sweatshirt (yellow, pink, blue, or gray work best)
-
Felt sheets (white, black, red, and your main shark color)
-
Cardboard (for the fin and tail)
-
Hot glue gun or fabric tape
-
Scissors (sharp fabric scissors or detail scissors)
-
Safety pins or fabric tape for attaching features
-
Black marker or sharpie for drawing details
-
Smooth foam balls or large googly eyes for the shark’s eyes
If you want a 3D look, you can use large cardboard pieces and paint them with spray or acrylic paint. For the eyes, paint foam balls with black circles for the irises. A box cutter or X-ACTO knife helps cut shapes and eye sockets. These tools make your costume look more realistic.
Tip: Wool or wool-blend felt holds its shape better and lasts longer than synthetic felt. If you want a costume that survives more than one party, go for these options.

-
Glitter felt or fabric paint for sparkle

Pinking shears or decorative scissors for fun edges

Extra felt for gills, nostrils, or a shark belly

DIY Baby Shark Costume Tutorial

Ready to dive in? This step-by-step tutorial will show you how to make a diy baby shark costume that’s easy to make, comfy, and perfect for any party. You’ll use a hoodie as your base, so your costume stays warm and simple. No sewing skills needed—just grab your hot glue gun, fabric tape, or safety pins. Let’s get started!
Shark Fin and Tail
The fin and tail give your baby shark costume its signature look. Here’s how you can make them:
-
Draw a large shark fin shape on a piece of cardboard. Make sure it’s tall enough to stand out but not too heavy for the hoodie.
-
Cut out the fin using scissors or a box cutter. Repeat for the tail, making a smaller, curved shape.
-
Cover both shapes with felt in your main shark color. Wrap the felt around the edges and glue it down for a smooth finish.
-
For extra strength, glue a second layer of cardboard to the base of the fin.
-
Attach the fin to the back of the hoodie using hot glue, fabric tape, or safety pins. Place the tail at the bottom back edge of the hoodie.
Tip: If you want the fin to stand up straight, add a strip of sturdy cardboard or a popsicle stick inside the fin before gluing.
Shark Face and Eyes
The face brings your diy baby shark costume to life. You can make the baby shark eyes and mouth look realistic with just a few tricks.
-
Cut two large circles from white felt for the eyes. You can use foam balls or large googly eyes for a 3D effect.
-
Place the eyes on either side of the hood’s center seam. Adjust the placement until they look lifelike, then glue them down.
-
For a more realistic look, cut black vinyl or felt into slightly off-round shapes for the pupils. Stick or glue these onto the white circles.
-
Draw or glue on small black felt nostrils above the mouth area.
-
Use a black marker to add details like eyebrows or extra lines for expression.
This method makes your diy baby shark hoodie tutorial stand out and gives your costume a fun, animated look.
Shark Teeth and Mouth
The mouth and teeth are the stars of any baby shark costume. Here’s how to make them safe and secure:
-
Cut a long strip of red felt for the gums. Use a template or freehand the shape to fit around the hood’s face opening.
-
Glue the red felt to the outside edge of the hood, leaving extra to wrap around for a clean finish.
-
Cut white felt into triangle shapes for the teeth. Make sure the points are not too sharp for safety.
-
Attach the teeth to the inside edge of the red felt, spacing them evenly.
-
Fold the extra red felt over the teeth and glue it down. This creates a dimensional gum and teeth effect that looks real and stays in place.
-
Felt teeth are soft and safe for kids. They stay attached to the hood, so you don’t have to worry about them falling off during play.
Attaching Features
Now it’s time to put it all together! You want your diy baby shark costume to be comfortable and secure.
-
Use hot glue or fabric tape for a no-sew finish. These methods work fast and hold strong.
-
Safety pins are great if you want to remove or adjust parts later.
-
Make sure the fin and tail are firmly attached to the hoodie. Test them by gently tugging to check they stay put.
-
For mitts or shoe covers, use elastic bands to keep them snug but easy to remove.
-
Check that all glued parts are cool and dry before wearing the costume.
Note: This tutorial is perfect for no-sew halloween costumes. You can finish your costume in under an hour, and it’s easy to make changes for different sizes or colors.
You now know how to make a diy baby shark costume that’s fun, safe, and totally unique. Show off your creativity and enjoy your new look!
How to Make a DIY Baby Shark Costume Unique
Pink DIY Baby Shark Costume
You can make your costume stand out with a pink diy baby shark costume. Start with a pink hoodie or sweatshirt as your base. Use pink felt for the fin, tail, and face details. Add white felt teeth and big eyes for a cute look. If you want extra sparkle, try glitter felt or fabric paint. Many kids love the pink version because it matches the Mommy Shark character from the song. This style works great for family halloween costumes, especially if you want to match with siblings or friends who choose other colors.
Tip: Let your child help pick out the shades of pink or add their name with fabric markers. This makes the costume feel special and unique.

Quick Tips for Busy Parents
You want your family halloween costumes to be safe and easy to make. Here are some quick tips:
-
Use flame-resistant materials for all costume parts.
-
Make sure hats and hoods fit well so kids can see clearly.
-
Choose non-toxic makeup instead of masks. Test it on a small area first.
-
Avoid sharp or long accessories. Soft felt fins and tails work best.
-
Use only skin-safe adhesives. Skip super glue or household glues.
-
Watch out for small parts that could be a choking hazard.
-
Adjust the costume size by using bigger or smaller hoodies. Add elastic bands for a snug fit.
Note: You can finish most costumes in under an hour. Let kids help with safe steps like picking colors or sticking on felt shapes. This makes the process fun and helps everyone feel included.
Troubleshooting and Tips
Fit and Comfort Fixes
You want your baby shark costume to feel good all night. Start by picking soft, breathable materials like cotton or fleece. These fabrics help prevent itchy skin. Make sure the hoodie fits just right. If it feels too tight, try a bigger size. If it feels too loose, add a belt or tuck in the extra fabric. Always check that the costume does not drag on the ground. This helps you avoid tripping.
Try a quick test run before the big event. Let your child wear the costume around the house. Watch for any spots that rub or pinch. You can fix these with a small patch of soft fabric or by adjusting the fit. Use velcro or zippers for easy on and off. This makes bathroom breaks and quick changes simple.
Tip: Skip masks that cover the eyes. Use face paint or felt shapes instead. This keeps your child’s vision clear and safe.
Repair and Reinforcement
Sometimes, costume parts like fins or tails come loose during play. You can keep them secure with a few tricks. Use extra hot glue or strong fabric tape on the base of each part. If you want even more strength, add a second layer of cardboard inside the fin or tail.
For active kids (or even pets!), try attaching fins and tails to a harness or belt. Introduce the costume slowly. Give treats or praise when your child wears it. This positive approach helps them feel comfortable and keeps the parts in place.
Here are some quick reinforcement ideas:
-
Double up on glue or tape at stress points.
-
Use safety pins for backup support.
-
Add a strip of sturdy cardboard inside the fin for extra hold.
Last-Minute Solutions
Costume emergencies happen! If something falls off or rips, don’t worry. You can fix most problems in minutes.
-
Use safety pins to reattach loose fins or tails.
-
Grab fabric tape or double-sided tape for quick fixes.
-
Patch small holes with extra felt or fabric scraps.
-
If a tooth falls off, glue it back with hot glue or fabric glue.
Note: Always keep a small repair kit with pins, tape, and glue handy. You’ll feel ready for anything!
