Ask the Bride -- Invitations for Attendants
Question: I'm not certain whether the wedding party generally, traditionally, recieves wedding invitations or not... --Misti Tucker
Answer: Yes, the attendants do normally receive wedding invitations. If you will be seeing them all around the time that you mail out the majority of the invitations, then you can give the invitation to them in person, or else you can mail them with the rest. It's a nice gesture to give your attendants their own invitations so that they can keep it as a memento of the wedding. Often the attendants would never even see the invitation if they didn't have their own!
When you're ordering your invitations, remember to include extras for your family, attendants, last minute additions to the guest list and some for yourself. Normally you should order 10-15% more than the actual number you will mail out.
