This might be a dumb question, but are you supposed to buy the flower girl's dress for her, or is that something the parents of the flower girl do? We are having my FH's niece, who is going to be 2.5 at the wedding, but lives across the country. I want to make sure they are involved in picking the dress because she's old enough to be particular about what she wears, but I also want to have a say. How is this supposed to work?
