Mine was covered in brewery bar towels,I always was the height of fashion
But wasn't that where you'd gone to sleep on them the night before and when they dried they'd stuck to you?
I don't think it makes any difference what you wear, as Sam says, it's how you behave on the bank that matters. Our club used to have evening matches and fish into darkness, each angler had a Colman or North Star (was it?) lamp lit up like a 100 watt bulb, but it was always on and never moved! Any boat on the Thames passing the match might have thought they were passing Blackpool during the illuminations, but they caught some big weights of roach and bream from not too far out at times. Yet the 'specie' guys (some, not all) wander around with head torches on, switching them off when not required, and wonder why their catches aren't as good.
I hand fed a shoal of chub once, about 50 or so fish from 2-5lbs, with pellets and I was wearing bright clothing (Hawaiin shirt, my normal summer wear
) and the fish were swimming through my shadow across the water. 'Keep off the skyline', yes, but only if you are moving about a lot.
