I lived in Ithaca for 5 years. And in the winter I never saw anyone dress like that. It must be a new form of insanity. Or some sort of TicTok challenge. Which is pretty much the same thing as insanity.
We lived in the Syracuse area and saw it all the time.
I think people figured they would just be going from a warm car toa warm store or house, so didn’t need it. Although I did see people strolling down the street dressed in summer clothes when it was snowing out. And that was years ago, so it’s been going on a long time.
The other pet peeve I have is parents who dress appropriately who are being followed by grade school kids in play clothes as if it’s summer. If you feel cold, they will. MAKE them dress appropriately. You’re the parent. Act like one.
