How to dress when heading to a game ?

[tnroundballref]

How do officials dress when arriving to a game (Varsity, College, Professional)?Â* Are there certain requirements in some associations?Â* I know our association offers nice Polo shirts for purchase and my crew wears them uniformly, however this is not mandatory.Â* I see some officials wearing a tie, but when someone else on the crew is in khakis and a t-shirt it looks awful.Â* How is this handled elsewhere?Â* Please advise.
