I always appreciate a man with a fine wardrobe and a good personal sense of style. At the same time, I'm glad I have neither. Stained loafers, mismatched socks, dockers, and a t shirt that you've recently dried your hands on work just as well with a flat cap. In fact, the flat cap imparts style to what I generally refer to as extreme casual clothing. The criterion for being extreme casual is whether you sleep in the clothes that you also conduct your daily affairs in. Changing socks and underwear daily is permissible.
I have always though those were groovy, I have never had one though.
I think they are as ugly as sin....... And no, I don't think that I will be wearing one.......
And then there's this kind of hard hat...Ball cap at work, resistol straw off work in summer, 10X felt in colder weather, only reason I wear a ball cap at work is because I am required to wear a hard hat and the bill on the hard hat don't block enough sun so I wear the ball cap under it. Wear the ball when hunting too.
