Wedding invitations are formal requests sent to guests to attend a couple's wedding ceremony. They typically include essential details such as the names of the couple, the date, time, and location of the event. Invitations can be designed in various styles, reflecting the theme or personality of the couple. In addition to the basic information, wedding invitations may also include RSVP details, dress code, and additional events like receptions or pre-wedding parties. Couples often choose to send out invitations several weeks or months in advance to ensure guests have enough time to make arrangements.
