Outfit advice!
I am always a huge fan of neutrals, earth tones, and jewel tones! I always recommend picking either one color and doing different shades of that color through out the family or picking 2 complimenting colors. I usually only recommend putting 1 or 2 family members in a subtle pattern depending on the size of your family. The one color I never recommend is bright white. It can shine super bright and just take over the photo. Both super dressy attire or simple casual attire photograph very nicely for family sessions. I always recommend to just be you!

Olive Green & Beige/Ivory

Mustard Yellow & Olive Green
Burnt Orange & Ivory
