There's something to be said for wearing suit and tie. It's a handy way to look "smartly/fashionably dressed" in a general context, that you have to put literally zero effort in thinking about. It's also, to some extent, an overt signal that you're committing to being professional and considerate of others - an often dismissed 'bourgeois' norm that's nevertheless a building block of society, if perhaps one that most people like to take for granted.
