So, you've booked a shoot and now you're stressing over what to wear. There was a time... at least a decade ago, that someone decided that everyone in a family shoot should wear white shirts and jeans or khaki pants. Well, people...that time has passed. For one thing, white really washes out the skin tones. Bright colors really liven up the shoot! The pictures below are a great example of what colors can do for the photos. The bright pink and blue on dad and the blue on his son match nicely with mom's pink shirt. Their daughter has on a white top but her skirt is pink and white. Had they all worn white tops, they would have blended in with the background and each other! Their attire isn't too busy either. Simple stripes along with solids.
If you are having a large family shoot, try to get some of the family to wear simple prints (small stripes, small flowers) and some to wear solids. Having a common color or two is best but not different shades of the same color. Keep away from white and black if at all possible, you'll be glad you did and your photographer will be too!
