Masquerading as a choir singer to a fancy dress party or for a play doesn't necessarily mean you have to buy or rent a costume -- you can affordably make your own at home. Many renditions of the classic choir robe exist, so choosing the colours and design is an important factor when creating your costume. Usually the bib of the robe is round or in the shape of a square or triangle, and its colour tends to be lighter than the robe itself. The simplicity of the costume makes it an easy and attractive creation, even in a pinch for time.
Measure the length of your body from your shoulders to your feet. Then spread your arms and measure the distance from your left hand, across your chest, to your right hand. Mark the measurements on the sheet of fabric (the dark sheet) that will serve as the bottom layer of the costume. Cut a rectangle according to these dimensions.
Lay the fabric on the floor and fold it diagonally so that it makes a triangular shape. Along the fold of fabric, locate the middle and draw a half-circle that is roughly half the size of your head. Cut out the shape to create a neck-hole.
Cut a square from the second sheet of fabric (the top sheet) with dimensions of roughly 60 cm by 60 cm (2 feet by 2 feet). Then cut a hole in the top sheet to match the hole in the bottom sheet.
Place the bottom sheet over your body so that it looks like triangle in front. Then place the top sheet over the bottom sheet and turn it so that a triangle hangs in front of you.
Pin the top layer to the bottom layer from beneath the fabric. Apply the pins only around the edges of the neck hole.
Draw the shape of a cross on the piece of felt and cut it out. Glue it to the middle of the top layer (the bib) so that it's on your chest.
Cut a piece of ribbon that equals the length from underneath the bib to the bottom of the robe. Glue the ribbon vertically down the middle of the front of the robe. Place the glue in dots about 2.5 cm (1 inch) apart.
For extra support, pin the shoulders of the top layer to the shoulders of the bottom layer. Create a page from a music book with notes on it to carry with you.
