Hi, I don't wear dresses anymore so my evening attire is all slacks and tops. I have multiple pairs of lightweight knits that don't wrinkle in black, grey, periwinkle . Various tops to go with them. I wear those slacks on all nights except formal. I have 2 pair of dressier pants, both palazzo style with dressier tops.
I also have a jumpsuit I bring too, just for a change up. It is red with white polka dots in a crepe material. I feel quite comfortable in that as well.
Your choices sound fine to me. Talbots stuff is very nice......and I do bring cargo crop pants but that is for excursions😀they are lightweight cotton.
