I have read both in order of height or order of importance. I'm not interested in trying to decide who is most important to me, in fact the idea is kind of appaling! But if I line them up by height does it go the shortest next to me and then on up? Or the tallest next to me and then down? We have some seriously tall groomsmen and a couple bridesmaids that are super tall too. One of my bridesmaids is actually 6' and I'm 5'2". I will be wearing 4" heels though. I can't believe I never even thought to ask or figure this out yet.
