If you are having a session with you and your family with your dog, wear neutral colors like those that occur naturally outdoors. Avoid whites, because I may ask you to sit down on the ground, and you will absolutely get dirty. Wear comfortable shoes because we will be doing some walking. If you wear shorts, a dress or skirt make sure it will cover you properly when you are seated. If your dog must wear a harness, a black or brown one will look much better in photos than bright colors.
