Which term describes an item that is carried or worn by a character, such as glasses or a wallet?

The term that best describes an item carried or worn by a character, such as glasses or a wallet, is "personal prop." Personal props refer to items that are integral to a character's identity or daily life and are typically held or worn by the actor to enhance the portrayal of the character. They play a crucial role in defining a character's personality, circumstances, or status within a performance.

Costume props, while similar, usually refer to items that are part of a character's costume but may not necessarily be used frequently in interaction. Set pieces are generally larger items that form part of the stage design and overall environment rather than personal items. Theatrical accessories is a broader term that could encompass various items but does not specifically highlight the intimate relationship between a character and the personal items they use. Thus, "personal prop" is the most accurate term for items that characters carry or wear, reinforcing their individuality and contributing to the storytelling.
