When someone hears the word mime, they usually imagine a person in striped clothes, their face painted white and a red beret on their head, pretending to be in a box. But, that isn't all mime is! The definition of mime is
The theatrical technique of suggesting action, character, or emotion without words, using only gesture, expression, and movement.
Elaborate props aren't usually used, but simple things such as chairs etc. are common. Costume is usually used to get the character across better.
