I'd probably fit in there as I tend to be overly formal in my attire. I wear white T-shirts, but only as an undershirt. I would never go out in public with just an undershirt as a shirt. It may have worked for Stanley Kowalski, but not for me.
I wear white t-shirts often, but they aren’t underwear. I’d be fine wearing a different colour.
but no pants?
But then, most of my town trips are to places like WalMart or to grab a gallon of milk. Eating out means McDonalds or Burger Sling. And in the heat of a southern Arizona day - I'm almost never out after dark - no one worries about my thick cowboy boots, jeans or white T-shirt.
But in the article, it is for an eating place in NY after 8PM (which is darn close to my bedtime!) and I find the restrictions totally understandable.
