I'm out of practice and what's "right" seems to have changed for so many occasions since Covid, where everything's got more casual.
That said I've always struggled for occasions that are somewhere between dressy and casual. I can do partywear, workwear and casual, but since smart jeans and a nice top died a death (a long time ago, when I would have worn them with heels) I have really struggled with what to wear for an event that's essentially casual but requires a bit of effort to look nice. E.g. a date in a pub or non fancy dinner.
What are you go tos? I like my wide leg jeans but struggle to put them with anything except a fitted tshirt and trainers.
