I bet some of the old MDs at New York Hospital still wear some ties. It was de rigueur 30 years ago but so many have stopped - among other things they are fomites since they can drag infection from one patient to another.What Paul didn't note is that his walk takes him through one of Manhattan's major business district. I usually note about 10% tie-wearers in that area - so not far off from Paul's estimate. Come up to my neighborhood - the Upper East Side - and the number drops to 5% during the week and 1% on weekends (and that's only 'cause I live near a large teaching hospital which seems to have a few older employees who still dress in suits or sport coats and ties).
It has been a couple of years since I have been in midtown and probably 5 years since I have been in the business district in London. Ties and suits were still pretty popular but hardly ubiquitous. As I have noted in other posts - the bankers and accountants have mostly stopped wearing them and now the lawyers and doctors too. Just leaves preachers and judges., as it's all just what I see on the street, the move away from suits and ties has accelerated in the last few years. As noted, you'll still see them in the biz districts - but they no longer dominate even there - and away from those areas, you only see a single percentage of men in them.
Weddings only if you are in it. And funerals just the staff and the preacher.I've also noted a rapid decline is in non-business situations. Other than weddings and funerals (and it's no longer a given that everyone will wear one at a wedding and the last few funerals I went to were well less than 50% suit and ties), I never see suits or ties and only a few men (like me) who still wear sport coats.
I always dress up at work so they don't ask me. I still wear a tie with suits but more often I find myself tieless with a sports jacket. I wear pocket squares usually with a bit of color in them in lieu of the tie. At least it gives some color.My standard not-summer - not work - outfit is chinos (occasionally jeans). buck or desert boots, OCBD, sweater and sport coat (not tie) and I hear - more and more each year - "why are you so dressed up?" I can't imagine the reaction I'd get if I added a tie or wore a suit.
