I have been looking over the proper way to address invitations, and it always seems to have the husband's name listed before the wife's name for married couples. However, what if the main person who I want to invite is the wife (and the husband would then be her guest), and I don't personally know the husband (or I don't know him very well), but I do know his name? Would I still have to put the husband's name first on the invitation, even if the husband doesn't know me yet? Or can the wife's name be listed first on the invitation because the wife knows me?
By the way, I am using only an outer envelope, no inner envelope.
