Basically any activity-appropriate clothing (per social, not practical, rules). In most cases I can’t be bothered figuring out what clothes to wear. I mean sure, a wedding or a funeral I know, but otherwise? A fancy restaurant? Lawyer meeting? Giving a talk? Who cares?

I go to board meetings in my normal clothes, and with my dog, and until my kid said something it didn’t even occur to me to do otherwise.

I do remember buying a car years ago and my wife commenting, “At home [europe] they wouldn’t even let you in the door”. In the Vally they just want to do business.
