Clothes help (kids)

[MandaT]

for this planned session.

I'm working on a 'themed' session for back to school. I'll be using a couple new little 'models' and need to get a clothing idea together for them.
They are 4-6 year olds, my DD is one of them and then, either another girl & boy, or possibly 2 boys (so 3-4 kids).

Link me up to some ideas. ("locally" we have Kohls, Ross, Target, Childrens Place, JCPenney, WM)

I have this dress ordered for DD:


Here is what I'm thinking, but don't want to get too matchy, matchy.
Boy: dark blue jeans/shorts for boy, either an orange or teal/light blue polo type shirt. Or brown shorts?
Girl: jean/brown capris & pink top ?
