What does a +1 mean for a wedding?

A +1 is a polite way of saying you may bring one additional person to the wedding. This person is often called a plus-one, a guest, or a date, depending on how the couple has phrased it. It does not mean you can bring two people, a child, or a friend you have not mentioned. It also does not give you the right to bring anyone you like without the couple's permission.

Whether you receive a +1 depends on the couple's budget, venue capacity, and how well they know your partner. Some couples invite all their single guests to bring a date, while others only invite long-term partners or spouses. If your invitation is addressed only to you, then you should assume no extra guest is included. If it says 'and guest' or 'plus one', then one additional person is welcome.

If you are unsure, it is fine to ask your parents or the couple directly. Keep the request brief and kind. Do not expect a +1 if you have just started dating someone new. Remember that the couple is balancing many wishes and practical limits when deciding who attends.
