So my mother is convinced that if she wears a long dress, than my FMIL would wear long. So she's hesitant to pick one out because she wants to make sure my FMIL would be comfortable. Am I crazy??? Do they need to wear similar styles? They are completely different sizes anyway! My mom is thin to average (?) sized and my FMIL is overweight, which is probably why my mom is trying to be sensitive. I'd ask my FMIL her opinions, but she's a little out there and probably won't plan her outfit more than one day in advance. I've given them both guidelines for colors (for picture purposes), they know how "formal" the wedding will be, but I don't think they should be concerned with each others styles. I say, wear whatever's comfortable. Right???
