Kind of unique situation, maybe, but our flower girl has two older sisters who we are letting also do something special in the wedding. I've offered to pay for her dress but also want to get dresses for the other two so they don't feel left out. I'm sort of ambivalent about the following, but if it were your wedding, how would you all feel about all three having the same dress ? I posted the link below, it's simple and would be cute with a little headband or something. Is there any written rule that the flower girl has to be the only one with her dress?
