In general, a plus one means a date. It doesn't mean bring along your BFF for a night of free drinks from an open bar. If you were invited with a plus one but can't find an actual date to bring, don't just assume it's fine to bring along a random friend.

What is a plus-one at a wedding? In general, the term “plus-one,” most commonly used in reference to weddings, grants an invited guest permission to bring someone with them to an event. When engaged couples allocate plus-ones, it's important to note that the plus-one does not apply to every guest.

Does a plus 1 have to be a partner?
