My fiance's and my friends are all different shapes, sizes, and heights. Is there a right or wrong way to pair groomsmen and bridesmaids so that they "look" and "feel" good around each other when walking down the aisle and taking pictures. Also, some of them know each other and some will be meeting for the first time. Is it best to pair the ones that know each other together, or am I altogether putting WAY too much thought into this?
