We go to London theatres quite a lot - people wear all sorts, though probably mostly what I'd call smart- casual But you could honestly go in jeans and not feel out of place. Ditto the sort of dress or whatnot you might wear to a smart restaurant.
We also went not long ago to a Classic FM concert at the Albert Hall - it was packed and the vast majority were dressed as above. But there were two girls very done up and wearing strappy evening-type dresses - nobody else in the whole place was wearing anything of the sort. I think they must have felt a mite out of place, though maybe they just enjoyed dressing up. I hope so.
