Here are my tips & suggestions to help guide you. There are also great suggestions here for what families or groups of people can wear. Generally though, I suggest that if you would like to be in some photos with your baby that you both wear plain, comfortable, unpatterned clothes. Layered clothes look create and create depth. Black or neutrals work best for adults so the focus is on faces and expressions. Ensure all cat or dog hair is removed from your tops especially if black as it will show up in your photos.
