If you've lost your wedding invitation, the first thing to check is whether you have already sent back the RSVP card.*
If you have already sent your RSVP (if it was sent), there’s no particular problem, and you don’t need to inform the bride and groom or the receptionist on the day.
However, if you don’t have the invitation, you won’t know the details of the venue or time...!!
In that case, here are three options you can take:*
① Ask friends or colleagues who are also guests (this seems to be the best option!)
② If you know the venue, call the location and inquire.
③ If you don’t know any of the other guests' contact information, you could explain your situation to the bride and groom, apologize, and directly ask for the details.
