Here's another great portrait session clothing idea; white pants and a denim shirt. The outfit works great because it's casual but gets dressed up by adding the heels and jewelry. This outfit would photograph beautifully as well. It's a fun, young, clothing option for high school seniors or hip Moms.
I always suggest, for family photo sessions, that Mom decide what she wants to wear first. We have the hardest time dressing ourselves, but finding an outfit we love for our children is much easier. Once you've decided on what you'd like to wear, simply coordinate your families' clothing selections and you're done!
