How do you ask for a plus-one if you didn't get one?

Choose a quiet moment to speak to the couple, either in person or by a short message. Say that you would love to bring a date and ask if there is any room. Keep it light and do not make it sound like a demand.

For example, you might say you have been seeing someone and would be glad to attend with them. If the couple explain that space or budget is tight, thank them and say you understand. Do not ask again if they have answered.

It is also okay to ask about the evening only, rather than the whole day. Some couples allow extra guests for the reception but not the ceremony. This can be a middle ground that works for everyone.

If the answer is no, try to attend on your own. Most couples keep plus-ones for partners they know well. Your presence matters more than a date. If you are worried about feeling alone, ask a friend from the wedding party to sit with you.

This is etiquette, not law, so the couple's wishes come first.
