Now that you've passed the test and have registered with USSF it's time to go out and buy your first uniform. The basic uniform for referees is a yellow shirt, black referee shorts, black socks and shoes. Though there are several places to buy uniforms, USSF is officially sponsored by Official Sports Inc., (view website) or print this flyer for a discount package on an Indiana Starter Kit. Your starter kit should include just about everything you need to work your matches. For completeness here is a short list: Uniform (Referee jersey and black shorts), watch with a timer, whistle, a pad of paper to keep score, a flipping coin, red and yellow cards and a set of flags.
