This came up somewhere else, so I thought I'd ask the etiquette board in its own post.
Is it standard etiquette to invite the parents of the wedding party?
My guest list is full because of my dad's work friends (whom I've never met), but I think my MOH's parents (who have known me since I was 5) should be invited. Should I also invite her adult sisters (who I've known since they were born)? I really want my MOH's parents to be there, but they're divorced, dad is remarried and has a stepdaughter, so I feel like standard etiquette would dictate inviting her mother, sister, father, new wife, and step-daughter.
Help me all-knowing etiquette women! TIA
