Activity for Laura

My sister is getting married next year and doesn't want to have the typical bridal party. But she did ask me to be her MOH and wants to ask two others to be "bridesmaids" but without the typical role of matching dresses, standing at the alter, etc....

Not sure if we should include sibling girlfriends or boyfriends in family photos.. Thoughts? I have considered doing one without and one with but I don't want to waste our time on our wedding day!
