I am the mother of the groom, 5’9″ and not particularly fond of my legs. I would like to wear a floor-length or tea-length dress for my son’s formal outdoor summer wedding. The mother of the bride is short and thinks she looks shorter in a floor length gown so she would like to wear a knee length dress. Will I look out of place if I wear a longer dress than the MOB. The bride says she doesn’t care, whatever I am comfortable in, but I sure don’t want to make any wedding etiquette mistakes. Any suggestions?
