So I'm finally to the point where I will start assembling and sending out invites. I tried to go through the FAQ at the top but it's just too long. So I have a few questions.
I'm doing just one envelope (no inner and outer envelope). Is it necessary to use surnames when addressing the invites, ie: Ms. Jane Smith?
Also, I did read this from the FAQ
Married Couple, same last name
outter envelope: Mr. and Mrs. John Smith
inner envelope: Mr. and Mrs. Smith
I am inviting a work friend and of course her husband. Since I am using just one envelope, I would address it as Mr. and Mrs. John Brown?
I understand it's "proper" to word it this way, but would it be huge faux paus if I addressed it as Sally and John Brown?
And lastly, a friend of mine recently started seeing someone and she's super excited about him (and I am too to see her so excited). Since they JUST started dating, how do I address the envelope so that she knows she is able to bring a date? I think it would be weird to put his name on the invite since they just started dating but assuming things go well with them, I want her to be able to bring him.
Thanks in advance!
