> People were trending less formal almost everywhere in the workplace, except NYC, SF and LA (or in high touch industries like real estate or law).
Sorry if this comes across as nitpicking but I'm curious what makes you think SF remains formal outside of high touch industries? AFAIK tech is the biggest industry in SF and formal clothes are far from expected there, you would not look out of place in a hoodie and shorts in an SF tech office (or even in some reasonably nice restaurants). In most tech offices you'd look like a bit of a weirdo dressed any more formal than business casual.
