Hi everyone. I'm actually posting for my cousin, who is getting married in October. I searched all of the website and couldn't find the right answer to my question (or I did and just didn't realize it). Her question is regarding my parents and my brother on their invitation. My parents are married and my brother has been dating a girl for over a year. Though my cousin has never met the girl (and therefore said she wouldn't feel comfortable addressing her by name on the invite), she would like the invitation to make it clear that my brother is welcome to invite a guest. Is there a proper way to word all of this on the invite? My brother still lives at home, so he and my parents will all be included on the same invitation. Thank you for your help!
