One of the most interesting things about the Harry Potter movies is their robes. Many children and adults are interested in dressing like their favorite Harry Potter character for Halloween and other holidays. However, Harry Potter costumes can be expensive to buy, and they are usually made of cheap fabrics as well. It is possible to design and make your own Harry Potter robe with these instructions. You will need at least one day to complete this project.

Measure the length of several different parts of the body. Since you are creating your own pattern it is important that you measure everything accurately. Measure the length from the shoulder to the floor, the shoulder to the wrist, the armpit to the wrist, the shoulder to the neck, across the chest, the armpit to the floor, and from the shoulder to the armpit.

Use the paper to draw out a robe outline. It is best to make a small version of the shapes that you intend to use with the dimensions written beside them before you create the full-sized version. You will need to make 2 body pieces and 2 sleeve pieces. To make the sleeve, you will take both arm measurements and put the smaller measurement on bottom. You can make them as full as you want. The edge that will connect to the body of the robe should be the same length as the shoulder to armpit measurement. The body should be constructed in two halves. The length will be the shoulder to floor measurement, the sides will be the armpit to floor measurement, the width should be the chest measurement. The neck measurement is the chest measurement divided by 2 and then subtracted by 6. Make the full-sized pattern after you have the shape you want.

Take the fabric and leave it just the way they gave it to you at the fabric store. The fabric will most often come folded in half. (If you want to wash the fabric, just wash, dry and fold it in half as it was when purchased.) Pin the paper pattern to the fabric and cut out the shapes with the fabric scissors. You will need to cut 2 sleeves and 2 body patterns.

Sew the 4 robe pieces together along the seam. 2 pieces make up the back, and 2 make the front. Only sew the front pieces together where they will meet under the arms. Leave the front open so the robe can be put on. Hem the bottom of the robe, and the 2 open sides. Sew the shoulder seams closed.

Sew the short ends of the sleeves into the arm holes of the robe. It is easiest to sew the sleeves on before the 2 sides are attached to each other. Once they are attached to the robe, sew the side seams together. Repeat for the other arm. Turn the robe right-side out.

Measure around the head from one shoulder to the other. Take this measurement and add 6. This will be the length of the hood. Design a pattern for the hood with the neck measurement for the side measurement, 25 to 30 inches for the top measurement (smaller for young children), and 12 inches for the bottom measurement. Draw a straight line from the top line to the bottom line. This will turn it into a kind of triangle. Cut the pattern from fabric.

Sew the angled lines together. Turn the hood right side out. Align the seam of the hood with the back seam of the robe. Sew into place with a few stitches. Align the edge of the neck portion of the hood with each edge of the neck on the robe. Sew into place. There will be excess fabric hanging loose. Gather the excess fabric and fold into pleats until the fabric fits inside of the neck of the robe. Make the same number of pleats for both sides. Sew the hood into the neckline of the robe. Your Harry Potter robe is now finished.


An experienced sewer is best for this project.


It is important to keep the paper scissors and fabric scissors separate. The paper dulls the blades, causing the fabric to cut unevenly.
