First off, my parent's have been divorced for a few years now, my dad has been with his girlfriend for almost 2 years. I'm not super close with her, but if I see her I will have a casual conversation with her. For the ceremony she will be sitting up next to my dad and mom, for the reception she will be sitting at the same table as my dad, mom, fmil, ffil.
She recently asked me if I want her to wear anything specific. I told her I'd think about it and let her know, because honestly, I have no idea!? I really don't care what she wears as long as it isn't sloppy looking but I don't want to be rude to her. I also don't want to let her wear a "mother of the bride/groom" dress because I feel like she be at the same position as my mom, even though I only met her 2 years ago. But I want her to feel included and important also.
What are you having your dad's girlfriend wearing??
