I'm a pilot and am visiting on the Friday (I'm working Saturday and Sunday). If it's sunny I'll be wearing shorts and a t-shirt, if it's not so sunny I'll be wearing jeans and a t-shirt.
I'm not there to sell or buy anything - just to look around, watch the show, chat to some people, etc.! Suit not required in my case.
Plus it's 'Enthusiasts Day' so I imagine some fairly nerdily-attired spotters will be in attendance!
