All this fuss about what to wear!!! I was there last week trying for a class 2 - I've got an eyesight issue which will be escalated to the medical sub committee to see if they will approve me.
You cant say but I'm not sure that if I turned up in t shirt and trainers I would have got the same attention. You see I was depending on the good doctors to take me seriously enough to make a case for me to get the class 2. I wore jeans and an open shirt, smart casual I think they call it......
So if you think you have no medical issues it does'nt matter but I would always recommend dressing more formally if in doubt. While I was in the waiting area most of the guys were dressed smartly - even if they had those white robes on!!!
