He can deliver a withering, umm, well, you know...
That's "blithering".
I can
be a "blithering" _____ .
I'll have to pull together some more casual photos than my suits.
Until then, for your further consideration...
Both hats are fedoras, Craig Schaeffers is beat up, but still a fedora. Only the father is wearing a suit, but it's a heavier wool suit and used as fishing attire.
Another from the same film (which had very accurate period costuming).
2 fedoras in different states of repair and a flat cap. That's casual men's wear right there and a
lot more classy than a ball cap. There are no clothes in that movie you couldn't wear today and still look "normal".
My thing is not so much "wear hats for the sake of wearing hats" but dressing with a bit of comfortable and practical mature
style (long pants and shirtsleeves, shoes or boots, not tennies, jacket when needed) even when you are relaxing and being casual, even out in the woods.
The culture of youth in this country since the Sixties has us all dressing like children (short pants and sneakers and ball caps) into our dotage instead of dressing like men when we grow up.
