How do you address envelopes to guests who are engaged? FI's college roommate is engaged and getting married in may. We are sending out our STD's for our August 7 wedding in the beginning of Jan. Since FI's roommate will not be married in January, do I address the envelope as Mr. So and So. By the time we send out our invitations, they will be maried, so I would then addres the invitation as Mr.. and Mrs. So and So. Is this correct?
Married on 8/7/10

Also, keep in mind that if the FI's friend appears on the guest list as a result of his relationship to your FI, the STD should be addressed to him first.

And I agree with berrytr - I also heard that the person you are closest to should be listed first on the invite (or STD in this case), regardless of sex.
