I think it's very important to wear one's achievements with pride and more importantly, for safety. On the drive to the airfield in my 911 RS 2.7, I would feel under-dressed if I didn't slip into my Sparco racewear for the journey. Once there, it wasn't that difficult to change quickly into a flying suit. I found the name-patch helped new students introduce themselves and my bars and wings let them know immediately that I was someone who could be trusted to give advice and guidance. Once aboard my PA28-180, pens, pencils and papers were organised and in their correct place and my passengers gained comfort from the professional image projected. At the end of the day, it's common sense!
