A few months ago my mother in law and i were talking about the wedding and she told me she was going to wear this: http://www.victoriantradingco.com/store/catalogimages/1a/i1585618.html
I told her that that would be fine, because it was very pretty and I didn't see a problem with it. Now a few months later stepping back and looking at the wedding i see both of our families (with the exception of my mom and her, the whole family is in the wedding) which means that they will be the only ones that don't match, which is fine, but my moms is going to match the bridal party. So my mother in law is going to wear this blue outfit and stick out like a sore thumb.
My mother in law hasn't bought the dress yet, should I ask her to match us or should I let her wear it since I told her a few months ago she could?
