I don’t see how this isn’t a massive net negative to you personally other than avoiding occasional odd conversation. You can have genuine conversations both personally and professionally with all sorts of people even if you don’t “dress like shit”. The expat versus immigrant thing is interesting but I assume most can see through that. Sorry to sound critical not really my intention but this is a very interesting approach. It makes the most sense if you’re already set in a great gig or already made your money, no?
