No one can forget the smooth moves of Left Shark from Katy Perry’s infamous Superbowl half-time show. Surprise the whole party in this full-body shark suit, which requires no sewing and can be assembled in a few hours. No matter how good (or bad) a dancer you are, this costume is sure to accentuate your every move.

Things You’ll Need

3 pool noodles
Duct tape in aqua blue
Aqua blue fleece, 4 yards
White fleece, 1 yard
Hot glue gun
Plastic baseball
Black sticky-backed felt, 8-by-10-inches
White sticky-backed felt, 8-by-10-inches
1/4-inch thick foam, 1/2 yard

Step 1: Cut the Pool Noodles
Cut two pool noodles at a 30-degree angle at each end so they fit together into a point, and then duct tape them together. Make a cut in the middle of each pool noodle and add another 8-inch piece of pool noodle to extend the sides. Duct tape these extensions to the noodles.

Step 2: Cover the Noodles with Tape
Cover the entire surface of the noodles in duct tape. This will prevent them from melting when the fabric is hot-glued to them.

Step 3: Cut the Aqua Fleece
Cut two pieces of aqua fleece in the same oval shape as the oval noodle structure except 1 inch bigger all around.

Step 4: Add the White Fleece
Cut an oval-shaped piece of white fleece 3 inches smaller than the blue fleece and glue it to the middle of one of the blue fleece pieces, turning under the raw edges by 1/2 inch as you go. Set aside the other blue fleece oval for later.

Step 5: Glue Fleece to the Noodles
Hot-glue the big piece of blue fleece to the edge of the oval pool noodle structure, leaving the raw edges exposed.

Step 6: Add a Gusset
Cut two pieces of blue fleece that measure 8 inches wide by as long as your yardage will allow. Hot-glue each piece on either side of your blue fleece, along the front edge, turning the fabric under 1/4 inch as you go to cover the raw edge of the blue fabric oval.

Step 7: Cut Gills
Using scissors, cut gills out of your black felt sheet. You’ll need a total of ten gills (five per side).

Step 8: Make a Shark Mouth
Cut a black felt mouth and 19 pointed teeth from white felt. Glue the teeth to the black felt mouth, ten to the top and nine to the bottom.

Step 9: Glue the Mouth to the Shark
Hot-glue the mouth a little higher than half-way up the middle of the front of the white fleece on the costume. Cut away the blue and white layers of fleece on the backside of the mouth so you can see through the felt mouth. This is to provide visibility for you while wearing the costume.

Step 10: Make the Eyes
Cut a plastic baseball in half, and then cut a piece of black felt larger enough to cover half of the ball. Make sure the black felt curves in a semi-circle and and notch one side of it every 1/4 inch. Glue this sheet of black felt to one half of the plastic ball, overlapping the notches to pull the felt taut. Glue a strip of aqua fleece to the top, over the overlapping black felt, creating an eyelid. Cut a little white circle and glue that to the black of the eye for the glint. Repeat on the other half of the plastic ball to make the other eye.

Step 11: Glue the Eyes to the Face
Add hot glue to the back of the fleece and stick the eyes on each side of the shark face — on the blue felt — a few inches above the mouth.

Step 12: Create the Shark Fins
Cut two blue fleece triangles, two white fleece triangles, and two triangles of 1/4-inch foam that are as long as your arms and about 20 inches wide at the base.

Step 13: Glue the Fins to the Body
Glue the white triangle fins to the backside of the gusset, right where your arms fall on each side. Place each foam triangle behind each white triangle, and then hot-glue the blue triangles around the two long sides of the white triangles, leaving the short sides open at the back, which is where you will slide your arms through to wear the costume.

Step 14: Add a Back to the Costume
Add the second blue oval to the back of the costume, turning under the gusset’s edge 1/4 inch and gluing it to the back side of the oval as shown in the photo. Sandwich the blue part of the fin to the oval where they meet.

Step 15: Add Fins to the Gusset
Pull the sticky backing off of the gills and stick five of them to each side of the gusset right below the eyes.

Step 16: Make the Shark Feet
Wear tights or slim fitting pants and put the costume on. Have someone else trim the gusset strips where they hit your shoes and tape the bottoms of the gussets to your shoes with the aqua tape. This will be the “legs” of your costume. You could also secure the gusset strips to your pant legs with a small piece of tape as well.

Now, strut your stuff in your new shark costume, and no need to worry about dance rehearsals.
