Before SF As a teen/young man, I learned from both my mother & father as well as 2 uncles & grandparents. They gave me more than enough information to start with. My own sartorial skills pretty much evolved mostly by observing what men in the banking district were wearing. On days off, I would also spend mornings or afternoons at the city hall court house, or in libraries, and observe what lawyers and 'intelligent' people wore, then copy that too. Throughout those years I also approached men hundreds of times to compliment them on whatever, and ask them where I could buy a nice shirt/suit/coat/shoes/tie like what they were wearing. almost 100% of the time they were happy to tell me, and appreciated the compliments. Ofcourse I would gasp at the prices when I went store browsing. Back in the 1970's / 1980's mid-range clothes were still of very good quality so that's what I bought. Today, with all the out-sourcing, it's hard to look great in low end clothes unless you are stunningly gorgeous.
