You made a good point to advise your client to choose the best clothing they feel comfortable wearing in a photo session. It is recommended to use neutral colors and soft fabric especially if there are children included. Also, you may want to suggest adding some additional accessories such as sunglasses, cowboy hats or even headbands. This should make the photo session very interesting and light. I would make sure to keep this in mind if we ever have one in our family. Thanks.
When styling a photo session, I like to start out with a basic color palette and go from there. It can help to have one “rock star” in the photos who carries a pattern in their outfit that the rest of the group’s clothing or accessories pulls from, while keeping everyone else’s outfits more simple. You can do this with a neutral and a few colorful brights, or try a softer palette that has different tonal ranges of the same shades.
