dressing an infant for summer?

JK
It seems more simple than for winter, but I'm sitting here wondering what I need to get our little one for the summer? What shoes should I get him? Like little strap on sandels? We will be going to the beach in North Carolina and it will be super hot... I know hats and sun protection but just short sleeve bodies and comfy shorts? 
I'm so used to dressing him for winter and now that the weather is getting warm... I want to get prepared
