Usually a pair of black dress trousers and a dark shirt or T-shirt. A pair of good boots and a leather jacket this time of year.
I see people wearing nice trousers and shirts with sneakers and it looks like this to me. Don't understand why they'd bother with a shirt if they're going to wear that kind of casual footwear.
Really, though. Just wear something that is whole and clean not "edgy" (i.e. Guy Fiery shirts) and it'll be fine. If you're shooting an event you dress the same as the people attending. Don't show up in jeans and T-shirt for a wedding even though that would be fine for a child's birthday party etc.
I don't understand why anyone would need to ask about this at all.
