Pinterest can be a GREAT tool for picking a colour palette, or inspiring outfits.
I've made a board that I've pinned some family outfits on, which can be found here:

I have an extensive collection of little girl and baby outfits ranging from 3 months to 14 yrs. Many of my women's dresses will work for both maternity and non maternity, and go up to size XL. The gallery below shows photos of women and little girls wearing my client closet outfits in their family sessions. The following galleries are more dresses that I offer. 

​Girls size 4-10+ (super flexible dresses fit a wide range of sizes) 

3-6 & 6-12 months +

Mommy & Me, Maternity and non Maternity Dresses (assorted sizes, fits most)
