coaches uniforms

[Little Jimmy]

Now that spring is actually here and there's no need for jackets, I am having some coaches want to be on the field with MLB, NFL, etc. t shirts on instead of some type of school uniform. For example we have a team who's school colors are predominantly orange, and they want to wear Orioles gear. Fed 3-5-3 states "school uniform". I don't expect each coach to match but I do think they need to have something with the school name on it (or something neutral, "khaki, black, white or grey".

What's it like in your hometown? If a team's colors were green and black, would you let them wear an Eagles shirt? Etc., etc.?
