How to make an adult frog costume

Updated July 19, 2017

Frogs are curious little creatures and they make an interesting choice for a costume. The great thing about the frog costume is that you could wear it to different fancy-dress themed parties. You can be an ordinary frog for a wildlife theme or Kermit the frog for a Muppets or puppets party. You could even claim to be a Prince Charming before you were kissed by your beloved for a fairy tale theme. It's fairly cheap and easy to make a frog costume from scratch. All you need are a few materials and some basic sewing skills.

Fold the 7ft. by 6ft. green fabric in half, so it measures 7ft. by 3ft. Lay the fabric on the floor, then lie on it so your top of covers the material. Your neck should lie along the 7ft. fold and the other 7ft. edge should be near your waist. Stretch your arms out to either side, so your hands reach out towards the 3ft. edges of the fabric on both sides and the tops of your arms are parallel with the top folded edge. Ask a friend to draw around your body with the pencil. Do not draw it too closely. Make it a loose outline, leaving a 2 inch gap all around your body. Do not draw an outline along the tops of your arms. Let the folded edge be the outline there. The outline shape should look like a large, fat T, with the folded edge being the top of the T. Do not draw an outline around your hands. Stop at the wrists.

At the wrists, draw the outline of a frog's webbed hand where your hand should be. Make it at about 10 in. by 10 in. in size. Do this for both hands.

Cut out along the outlines. Leave the fold intact and do not cut along it because you are making a green, long-sleeved top and the fold will form the top seams of your arms. You should have a body shape with an arm pointing out each side horizontally at 90 degrees. Each arm should have a webbed hand on the end.

Sew up the left side of the body using the backstitch. Start at the bottom and when you reach the armpit sew along the left underarm. Finally, sew together the edges of webbed hand. Repeat on the right side. The bottom of the top should still be unstitched.

Cut a 10 in. diameter hole in the centre of the fold at the top of the fabric. This is for your head to go through. Turn the top inside out so the stitching and rough edges are on the inside. Your top is complete.

Lay the two 4ft. by 4ft. pieces of green fabric exactly on top of each other on the floor. Lie down on the fabric as before, but this time place your lower body over the fabric. Your waist should lie over one edge and your feet should be near the opposite edge. Ask a friend to draw a rough outline around you as before. The outline will look like a pair of trousers.

Cut out both pieces along the outline. Sew the two pieces of fabric together along the left outer edge of the left leg using the backstitch. Now sew the material together along the left inner leg. Repeat on both sides of the right leg. Turn the trousers inside out so the rough edges and stitching are on the inside. Your trousers are complete.

Cut a 10 in. diameter semi circle from the green felt. Cut it in half so you have two semicircles.

Cut a 6 in. diameter circle from the white felt. Cut it in half so you have two semicircles.

Place a white semicircle on top of a green one. Line up the two straight edges at the bottom. Glue the white semicircle in place then repeat with the other two semicircles.

Draw a 1 in. diameter black semicircle at the straight-edged side of a white semicircle using the fabric pen. Repeat on the other white semicircle.

Glue the straight-edged base of one of the green and white semicircles to the left side of the green plastic head band. Glue the other one to the right side of the head band. These are your frog eyes.

Wear your green trousers and the green top with the webbed hands at the ends of your arms. Put the head band on your head. Paint your face with green face paint.


If you have a pair of green trousers or a long-sleeved green T-shirt, wear those instead of making the costume if you wish. Make the frog's hands from green fabric and sew them to the wrists of your T-shirt.
