Here is some guidance as you build your uniform:
It is worth noting that some sites do offer starter packages.
Hat: Black with white piping.
Shirt (short and long sleeve depending on weather): High School and Youth Lacrosse Officials currently wear 1″ stripes in short and long sleeve shirt. In case of poor weather, striped jackets may also be worn.
Shorts: All black shorts/with belt loops. No cargo pockets.
Long Pants: Solid black with belt loops.
Shoes/Socks: Full black cleats or turf shoes. Solid black ankle socks, when wearing black shorts.
Whistle: Most prefer finger whistles, some use a lanyard from neck for face-offs and restarts. Fox 40 is best practice sound.
Penalty Flags: Two yellow/gold penalty flags.
Scorecard: Lacrosse Officials scorecard. Some are even cut to measure the head of a stick per rules requirements. Pencil: Small pencil for keeping track of important game information. Most officials use a rubber band or something similar to keep it with the scorecard.
Timer: High School and higher level youth games require us to keep track of the time it takes a team to clear the ball from their defensive half of the field, with a new possession, to their offensive half of the field in 20 seconds. Boys officials use a timer. Manufacturers make a small box worn on the belt. By flipping a toggle switch it starts a 20 second timer that buzzes when 20 seconds elapses. Some manufacturers even include 1 minute and 40 seconds on the timer to help with timeouts and quarter breaks.
