In regards to the OP, dress however you want. A majority of fly fishermen don't care.
Totally using "googan"... Hard to find em in our sport though, I feel. Some guy who just blew $1300 bucks at Orvis and looks like it probably cares enough about the sport to learn how to use all of that gear, and who hasn't been at that point in their fly-fishing life? Hard to fault enthusiasm... This is also a sport that you can't fake, and most folks like that are an opportunity to help mold the future anglers.
Talk to them, take a minute and put em on a fish, show them that casting a couple of feet to the right might help, show them the proper way to handle a small native trout. And if they ask about keeping fish, tell them without judgement why you choose not to, and your attitude can go a long way in teaching them to respect the sport and the fish.
What's almost more annoying is people who make comments on a noob to the sport. Those guys that think being a guide for a summer makes them an authority on everything fly-fishing related... I know a couple of old guys around here in TX and OK who still fly-fish in jeans and white t-shirts that could whip the pants off of a lot of good fisherman I know. I thought there was no way that these guys were serious fisherman, but I was wrong. Appearances 'round here can be very deceiving.
