Cats wigs are generally close fitting, and need to be secured firmly to not fly off during wear. This is achieved by wigs being fitted to individual actors, careful preparation before putting on the wig, and the wig lace itself is glued to the actor's face. A wig cap is worn under the wig, this holds the actor's hair in place, and protects the valuable wig from oils and products from the hair. Cosplayers may not be dancing the Jellicle Ball, but are likely to be playing around, dancing and posing in unlikely angles, so securing a cosplay wig is as important as for performance.
