My wonderful FMIL asked me what color I want her to wear to the wedding, and I didn't really know what to say. I feel so uncomfortable telling other people what to wear - I even had trouble giving my bridesmaids guidelines because I just want everyone to be happy and comfortable. I told FMIL that my mom was wearing a long, gold dress and that she's welcome to wear any color she wants. She said she doesn't want to clash with the wedding colors, so I told her any fall colors would be good. Overall, it was kind of an awkward conversation because I didn't feel very helpful. How was this conversation supposed to go? Do people tell the mother of the groom what color to wear?
