How to make an Oompa Loompa costume for a child

Updated November 21, 2016

Oompa Loompas are the colourful workers in Willy Wonka's chocolate factory. In the 1971 movie, "Willy Wonka & the Chocolate Factory," Oompa Loompas were portrayed as orange-skinned, green-haired little people who wore white trousers with suspenders and brown shirts with striped collars and cuffs. The short stature of the Oompa Loompas makes this costume well-suited for children.

Lay a pair of child's trousers onto a folded piece of thick, white fabric. Trace around the trousers leaving a 5 cm (2 inch) border between the trousers and your line.

Cut the folded fabric along the line to create two trouser-shaped pieces of fabric. Place the pieces right-side together and sew along the outer edge of the trouser legs from the waist to the ankle using a 1.25 cm (1/2 inch) seam allowance. Sew the inside of each pant leg and along the crotch as well and turn the trousers inside out.

Fold about 2.5 cm (1 inch) of fabric at the top of the trousers and the bottom of each trouser leg inside and sew along the fold to finish the edges of the trousers.

Hold a tape measure 8 cm (a few inches) off-centre at the child's waist and drape the tape measure across the child's opposite shoulder and down to the back of the child's waistline. Record this measurement and add 13 cm (5 inches).

Cut two strips of white fabric about 7.5 to 10 cm (3 to 4 inches) wide and the length of the final number from step three. These will form the suspenders of the Oompa Loompa costume.

Sew the strips to the back waistline of the trousers at a slight angle so that the strips will cross on the front of the child's chest before being secured to the front of the trousers. Have the child wear the trousers while you pin the strips in place if necessary.

Mark the spot on the front of the trousers where each suspender meets the waistline about 2.5 cm (1 inch) from the top of the trousers. Sew a large button to each of these marks.

Cut a slit in the suspender for the button and trim the edges of the suspenders so that they do not hang down past the buttons more than 2.5 cm (1 inch).

Apply white fabric paint to the collar and cuffs of a brown turtleneck to create the striped look of an Oompa Loompa's shirt. Lay the shirt flat while the paint dries to avoid drips or smears.

Purchase a pair of white gloves to complete the Oompa Loompa costume.


Oompa Loompas are identified not only by their clothing but also by their orange skin and green hair. Paint your child's face with orange Halloween make-up and use a green wig or colour his or her hair with temporary green hairspray.
