This video demonstrates how to matte down your pointe shoes for a recital or performance. For this, you will need a makeup brush and a container of translucent loose face powder. You may cut the powder in half, adding baby powder to it. This will lighten the powder a bit.
Dip your brush in the powder, and brush the powder over your shoes. Coat the shoes and the ribbons in powder, layering it on. Brush off the excess. Continue applying it, until the shine is gone. This will darken the fabric.
Donít forget to do the elastic on the shoe as well. Try to avoid getting it on the bottom of your shoes. It may make them slippery. This should remove the excess shine for performance.
