Black socks with black shorts, to quote Lucy from Peanuts:
"aaaagggggghhhhhhhhh!!!!!!!!!!!!!"
If you attend an officials camp, wear a v-neck shirt. If you are officiating an AAU or YBOA national tournament, there will be a prescribed uniform. If you are officiating in local tournaments, team camps, or summer leagues either a v-neck or collared shirt is fine. Personally, my collared shirts are still in excellent condidtion and I wear them in local tournaments, team camps, or summer leagues. Black shorts with white socks are fine too.
