Folkstyle Uniform Guidelines: 
 

Singlets with under briefs or a two-piece uniform is required. Guidelines for the two-piece uniforms are as follows: wrestlers can wear compression or board shorts and a tight-fitting sleeveless, short, or long sleeve shirt. The shorts shall not be excessively baggy or have pockets, buttons, or snaps.

Mouth guards are not required for wrestlers (even wrestlers with braces), but are highly recommended.
