Deciding what to wear for your senior portrait session is a task well worth your time and effort. I always recommend picking out outfits at least a week or two before hand and laying everyone's outfit and accessories out to see all together. Wash and iron a day or two before your session so that you can spend time before your session making sure everyone in the family looks clean and neat. 

And this pinterest board is FULL of wonderful ideas!
