MY MOH and I were working on a guest list for my bachelorette party recently and she said I should invite my mom. We are just planning on going to a dueling piano bar, which only gets slightly crass! haha I'm also planning on inviting FI's brother's wife. Does this mean I should also invite my FMIL? I honestly don't really want her to go, but think I should invite her if I'm inviting my mom and my future sister in law... Thoughts?
