inviting my future MIL to try on dresses?

my fiancé and I just started wedding planning (yay!!) and obviously part of that is trying on dresses. My mom and I grew up watching say yes to the dress and I just made an appointment at one of the shops, which I’m super excited for. I also want to invite my future MIL to try on dresses. even if she doesn’t want to travel 10+ hours round trip just to watch me try on clothes, I’d love to extend an invitation to her. I just feel like my mom will give me grief about it - she constantly complains that MIL has two kids (both boys) to see get married but she only has one daughter (me). She’s going to have to get over it, but I will also need to ask her if MIL can stay in their house too, which I don’t want to overstep about. What would/did you do in a situation like this? I want my mom there but I don’t want her to ruin it.
