I don't really think inner envelopes are necessary (and really don't want to use them because it's more money and kind of a waste?) BUT I am concerned about people knowing who exactly is invited to the wedding. I'm afraid that I won't be able to fit all of the names for each invite on the outer envelope with the address.
We are doing online RSVPs through the knot, and it lists the people who are included on the invite when you RSVP...is this clear enough for who is invited? If you were RSVPing this way, would you know not to bring kids/a plus one, or should I get inner envelopes? (picture of what it looks like when you RSVP for those who haven't used the knot!)
