Q: What's the etiquette regarding inviting co-workers? Can we give them a group invitation?
A: It is nice to invite all your co-workers, but don't feel like you have to. If you work in a small office or with a very tight knit group, you'll probably want to invite everyone or no one. Otherwise, invite those co-workers you socialized with outside of work and your immediate supervisor. It is polite to send everyone you invite their own invitation.

Q: How do we let guests know we want cash instead of gifts?
A: It isn't appropriate to request anything specific as gifts, particularly in your invitation. Registries offer a polite suggestion. If you are asked, you can tell guests your preference. You can also inform family and close friends so they can answer the same question if asked. Even if you prefer cash, register for at least some gifts -- some guests are going to want to give you presents. You can also register for things like your honeymoon or even a down payment on a house

Q: Should the groom's parents be included on the invite if the bride's parents are paying?
A: Parents don't need to pay for the wedding to be included on the invitations. Today, more and more couples are paying for their own weddings and still honoring their parents by including them on the invitation. It's up to you and your families.

Q: How do I address my invitations?
A: Etiquette requires that the outer envelope be addressed in black, and include full names, titles and addresses of the guests. Inner envelopes always are left unsealed, and do not include first names or addresses.

Q: When should invitations be sent?
A: Invitations should be mailed six to eight weeks prior to the wedding, say experts, and wedding announcements the day of the wedding or shortly thereafter. Make sure you have a complete invitation weighed at the post office before affixing stamps so you know whether additional postage is necessary.
