We will be having my FH's neices (ages 6 & 8) as our flower girls in the wedding. I want to pick dresses for them that are flower girl appropriate, yet not too young-looking. I don't know any girls that age, so I'm not sure what kind of dresses are age appropriate. I also want to keep costs down as their parents will both be in the wedding, so they're already investing enough money on our big day. Does anyone have any suggestions? Thanks!
