My mom has already ordered her dress for my July wedding. It is a floor length, berry colored, off the shoulder number that really looks good on her rounded bodytype. My FMIL knows that my mom has a floor length, but keeps pushing a short dress that she found (I have no idea what it looks like). At this point, I don't want to pull the Bridezilla card and say she has to get a long dress. But at the same time, this is my FMIL's first wedding and she keeps saying she "doesn't know what to do about weddings". So this makes me think that she just needs direction. But then again, if she already knows everything about my mom's dress, why is she pushing so hard for her direction and not ours? There are a few emotional complexities with the whole relationship that I have with her, and I don't know if that's clouding my judgement... Should I put my foot down and say it has to be long? Or let her have a short dress?
