What To Wear In Yellowstone In July

I’m planning a trip to Yellowstone in July and I’m not sure what to wear. I know that the weather can be unpredictable, so I’m looking for some advice on what I should pack. I’m thinking of bringing a variety of layers, including a rain jacket, a fleece, and a warm hat. I’m also considering bringing some lightweight pants and shorts, as well as a few long-sleeved shirts. I’m a bit concerned about the possibility of getting cold, so I’m also thinking of bringing a few sweaters and a warm coat. I’m also wondering if I should bring some waterproof shoes. Any advice would be greatly appreciated!
