I moved the PNW in 2012 and to deal with the incessant rain, my wife bought me a brown fedora. Nobody wears brown fedora's anymore. But I do, and you'd be shocked at the number of compliments I've received ("Nice hat!" or "I like your hat!") and the number of conversations it's started.

This has been the source of some comic misunderstandings, whereby an American bloke says they are/like wearing suspenders, and the listener then assumes they are coming out as transvestite.
My lecturer for assembly / low level computing used to wear braces, I enjoyed the look (and he certainly didn't seem to care what other people thought). As others have said, where what you want!
I get the feeling that these pictures were taken after the fellow passed by in the street and give them a “Good day!” or similar.
You can see various expressions, some which say “and a good day to YOU young man” from some of the older guys to a “hmmph good day” from some of the well dressed women.
