The dress code is formal, but make sure you are comfortable! If you attended the church wedding last year, you're welcome to wear the same thing (as some plan to do).
All adult attendees (to the best of our knowledge) should be vaccinated by the time of the wedding. The vaccine rollout is moving a little slower in Mexico, so we will let folks know if we expect differently.
Thank you but no need! We already received gifts for our ceremony in October 2020, and you traveling to the wedding is more than enough!
