My FMIL wants to wear a tea length dress and my mom wants to wear a gown. my FMIL is very simple, she doesn't really like to dress up much and doesn't wear too much makeup. She wants to wear a black tea length dress but I'm wondering if its going to make her look like just a guest instead of the grooms mother and if its going to make her look like shes going to a funeral. Anyone else have this problem or any suggestions? Do you think its going to look funny?
