What to Wear to outdoor July wedding?

Looking for advice on what to wear to an outdoor wedding in July. The reception is outside with a dinner inside after. The dress code is cocktail. I want to be fancy enough but not too fancy and still wear something that will keep me cool. I’m finding lots of satin dresses that I’m worried will just stick to me in the heat. This is my favorite so far, but I’ve got a loooonnggg list I’ve been looking through. Let me know if you have any more ideas. Thanks!
