Going to a wedding by yourself may seem like a drag, but asking the couple if you can bring a plus-one either before or after receiving your RSVP card is an easy way to be rude without knowing it. It costs money to host people at a wedding, and those close to the couple need to be prioritized. Asking the couple if you can bring someone just puts both of you in an awkward spot. And, please, don’t just bring your friend as a plus-one without even asking.
