Question:
When in a match can you wear small white socks over the original colours of your kit like so many players do in the premiership?
USSF answer (February 16, 2010):
In theory, never, unless all players on a side wear them. Each player’s kit (other than the goalkeeper’s) is expected to be exactly like his/her teammates’ kit as regards color and the color of any under- or overgarments.
