What should not be included in the attire of wrestlers during a match?

Including jewelry for aesthetic purposes in a wrestler's attire during a match is not allowed due to safety concerns. Jewelry can pose risks for both the wearer and their opponent, as it may become a hazard during grappling and movement. For example, earrings or necklaces could lead to cuts, bruises, or entanglements that can disrupt the match or cause injury.

In contrast, approved wrestling shoes, leg/arm sleeves, and headgear serve functional purposes and are specifically designed for use in wrestling. Approved shoes provide the necessary grip and support on the mat, sleeves can help during matches or provide compression and support, and headgear is essential for protecting the ears from injuries. These items are not only acceptable but often essential for both the performance and safety of the wrestlers.
