Okay, so I've read countless articles and forum posts about who to invite to the rehearsal dinner and almost all of them say that it's rude not to invite people's significant others/spouses. I understand the etiquette here, but after my fiance and I looked at the list of parents, grandparents, wedding party, the parents of the kids who are in the wedding, and other people who would be present at the rehearsal (readers, musicians), the number is at about 30. After factoring in everyone's sig. others/spouses, the number is around 50. Bottom line: would it be wrong to not invite sig. others/spouses? I don't want this to turn into a "wedding before the wedding," plus I'm trying to keep my future in-laws in mind as they are paying for the dinner but they aren't very well-off, financially speaking. Also, do readers and musicians need to be at the rehearsal? Thanks!
