Should my mother and my fiances mother wear dresses of the same color as my bridesmaids gowns?
Not unless they happen to like that color. The only rule for your mothers’ dresses is that they be similar to each other in length and formality. If your mother is wearing a short silk dress, your fiance’s mother shouldn’t wear a long, sequined gown. Usually the bride’s mother chooses a dress that is in keeping with the formality of the wedding. The groom’s mother consults the bride’s mother and then chooses a comparable dress.
