So FH and I are going to require proof of a negative covid test for our wedding. (Guests will be able to email results or show at the door) We are looking for ideas on how to notify people, and also looking for lighthearted and loving phrasing. We have some family concerned that this will come off "offensive" to our middle/older aged guests, so really want to find a lovely way to phrase that this will be a requirement.
(NOT looking for any covid related opinions, this is simply a phrasing issue)
