I am most commonly in jeans (nice jeans) and an oxford cloth shirt.
Having slept on the ATL floor, I come dressed for the context.
Actually, its also appropriate dress for the refreshments served... peanuts and cheap beer... see:

As for etiquette... Rule no. 1, do not ask the FA for both of the only two bottles of the Glenlivet that DL graciously provides for the FC cart.
