Question:
With the new requirement for undergarments being the same color as the uniform, is it required that all players wear undergarments or can some players wear undergarments and others not wear undergarments.
USSF answer (April 1, 2008):
The requirement for matching colors between undergarments applies only to those players who actually wear the undergarments in question. One would assume that all players wear some sort of undergarments, but we are concerned only with those that show.
