I've been mainly working on my casual wardrobe since kids, so I still don't have many dressy options, especially for warmer weather. I am going to the opera next week and I need help putting together an outfit... nothing fancy, just appropriate, since there are very few things to work with. First, are white pants suitable for an evening event? Something along these lines:

I'd have to borrow a clutch from my mom, and I am still not sure what to wear over the button down if it gets cold.

There is also this pair of pants, and I could wear a white blouse and a black blazer. Or what about this top:

but I have no idea how to accessorize. (I would wear different shoes with these pants, I just didn't want to change)

Any thoughts? If it gets cold again, I guess I could also do black pants/white shirt with my houndstooth vest that has been featured here many times, except the vest is wool and might be too wintery. Oh and please excuse the hair!
Thank you very much!
