Hmmm..to dress like the gentleman you speak of--or to look as if one leaped from the cover of an Orvis catalog? I love both kilts and flyfishing. If I expect the water to be cold and deep and I'm wading through it, then I wear waders. However I wear kilts often while flyfishing when the water isn't cold enough to cause hypothermia. The cool water feels therapeutic on this old athlete's knees.

A waistcoat and tie might be a bit much for some, but so is some of the comical 'fly gear' looks I've seen folks splash into a stream wearing. To each their own.
