First date-what to wear?

I’m going on a first date with a guy that’s quite attractive and well groomed and dressed. We lost touch but always thought of each other, then he contacted me and we decided to go out. It’s hot here. I need to find a middle ground, something smart casual, but comfortable in the summer heat. Should I wear a linen, floral midi dress? Should I wear any jewellery or makeup, or is that too much?
