Let me start by saying thank you guys for the help you've already given me so far through reading the threads - I am in my second year, 20 years old, and using your experience is very valuable. So far I have experience doing intramurals, a high school churche league in which many local varsity players play in, and youth rec ball.
I have not yet joined my association but will in the near future - that is why I am asking here and not contacting them for this. I want to gather everything that I need to be "official"

Pants, shirt (I have a shirt but I don't know if it is highschool approved), shoes, nfhs rule and case book, etc. I realize different associations in different states might have different standards, but I figured I could get decent help regardless
I just built these shoes on NikeID, and I'm not sure if the white NIKE is allowed - if not, can I just sharpie it?
Help with the other equipment would be great. Thanks
