New rules for Jerseys worn at games:

National Federation of State High School Associations

The home team shall wear dark jerseys and socks (dark is defined as any color which contrasts with white), and the visiting team shall wear solid white jerseys and solid white socks. Prior to and during the game, jerseys shall be tucked into the shorts, unless manufactured to be worn outside.

b. Both socks shall be the same color, with the home team wearing socks of a single dominant color, but not necessarily the color of the jersey and the visiting team wearing solid white sock. If tape or a similar material (stays/ straps) is applied externally to the socks, it must be of similar color as that part of the sock to which it is applied.
