What should I wear tomorrow night?

I’m travelling to the central coast on Sunday afternoon. That night, I’m out with two friends for dinner. It’ll be cooler out there, by the water. By then. It’s autumn now. Are a green gingham blouse, black trousers and navy skecher slipper shoes appropriate? I thought I could wear my navy blue, bulky cardigan over the blouse. To stay warm.
