I just found out the other day that my future MIL is wearing a top and skirt that she purchased several months ago (before we were even engaged) to our wedding. I'm not sure exactly what it looks like (she tried to explain it to me, but it sounds complicated, and she had a hard time doing it). I asked her if it was relatively dressy, as this is a pretty formal wedding. She said yes, it was. Okay. Cool. Now, my future MIL is in her mid-70s and is not the epitome of fashion, mind you, but that's okay too. What I'm bothered by is that she just told me that her top/skirt combo is the same color as my bridesmaids' dresses, and she's so glad I picked that color so that everyone would match. Well, I really don't want her to match the bridesmaids. My mother is not planning on matching the maids. I like the color I chose, but I wish I would have known the color of her outfit before I chose that color for my wedding. I'd like to ask her to wear something different, but I know I can't. I recognize that I'm probably overreacting, but I can't seem to shake it. Any advice?
