Choosing outfits doesn't have to be hard or overwhelming. Having a couple of colors selected for your pictures allows more options for your family. Also, try to pick out fun clothes that will show off your family's personalities. And remember, not everyone has to match exactly unless that is your family tradition. It adds more interest when choosing coordinating outfits that tie your chosen colors together. Matching outfits tend to make the photo look sterile.
You will want to avoid wearing all black and all-white clothing; they don't photograph well as stand-alone colors. In addition, these colors can cause you to lose details in the photo.
You will want to avoid any clothing with large graphics or text, even if it is a favorite shirt. It can be distracting in the photo. Instead, opt for a fitted – t-shirt. Plain tees are always great options; you can dress them up with scarves, belts, sweaters, etc.
Keep your photos interesting by adding different textures, patterns, and accessories. But, of course, you will want to keep your textures the same. For example, you don't want everyone in flannel and one person wearing a summer dress.
And speaking of accessories, don't forget about your feet. If your photoshoot will have full body shots, make sure that you have picked out shoes that match your outfits.
