Teams are strongly encouraged to review this document and the USA Volleyball Rules Book prior to purchasing uniforms. If you have questions about the legality of uniforms, please contact your Region Office or Region Officials/Referee Chair. If your team(s) will be attending any National events (bid tournaments, national qualifiers, etc.), USAV has developed a new website to allow teams to submit jerseys for approval (https://usavolleyball.org/resources-for-clubs/) Scroll down to Uniform Approval. The USAV Rules Interpreter will review your jersey designs and provide an approval form indicating what jerseys may be worn in combination with each other. If any jerseys are illegal, this information will also be provided.
