How many other Brides having Adult Flower girls? I asked my younger sister, who's relationship I been mending, to walk with her daughter in our wedding as a Flower Girl too, she agrees too it and I personally thinks it's cute. When I announce my wedding party to my bridesmaids they all were kind of a shocked I chose her to be one so I think she kind of was embarrassed about it, but I'm not sure. I'm so untraditional so I was cool with it. Are there any other Adult flower girls out there or have you been to a wedding with one? Should I have some kind of "smoothing over" talk with her about it?
