No Mask, No Come.

"To ensure the safety of all our guests, safety guidelines, including the usage of masks, will be strictly enforced." Or something to that effect.

I get where you're coming from - believe me. I know it's incredibly frustrating and feels like such a basic ask. Same page.
I haven't had my wedding yet, so I can't tell you whether my compliance efforts will produce the desired results.
But here's my 2 cents, and what I'm planning to do as well:We added all the "yes" ppl to a FB event, so we'll pass on the info like this. I plan on focusing on that people love us, we love them and we want everyone to *be* as safe as they can be at our event. (IDK about you guys, sometimes "feel safe" can irk me?) That wearing a mask to our event when you're not eating/ drinking means you respect us and the other guests. That each guest should feel *empowered* to control their space - move away from those not wearing masks or politely ask them to pull up their masks. That I will not be hugging ppl, because I care about them, and I will walk away if you're not wearing a mask because I care about myself.I'm going to put a poll to ask if ppl need me to purchase them (or they can DM), but also make it fun and ask ppl to be creative and coordinate their masks to their outfit if they want! I'm also planning to point out that bandanas and scarves aren't ideal - they should fit snuggly around the edges and have a few layers, etc. I know it can feel cathartic to tell people off. I am a petty queen in many ways. But you're looking for compliance above all else, right? The best way to get that is to be clear, calm and consistent.And you can always be petty on the forums. 😂✌️

Personally, I would post it on your wedding website, and also have some disposable masks available for those who don’t see your message, or who simply forgot to bring their masks. It happens. There is absolutely no need to be rude about it, unless someone puts up a fight about it day of. Then you have the right to refuse entry to your event.

View Quoted Comment I agree with this. Definitely have some at your event on hand in case.

Maybe something simple like.... “We look forward to celebrating our wedding with you. So, for the safety of everyone present, only guests wearing masks will be allowed entrance.”

View Quoted Comment I agree with having some avail but I would still put it on the invitation. I have never looked at a wedding website once to be honest. I look for all pertinent info on the invite. I even say this working at a high school and being the graduation coordinator that no matter how much information we put on our school website for people to read you'd be surprised how many people don't think to look at the website for information. If we did not send out a remind.com lot of students and parents wouldn't know anything. That's my opinion because it sounds like this is an important rule for you.

I would have some available and post a sign.
If you haven’t already mailed invitations I would include an insert regarding Covid and your mask policy. At the very least post it on your website.

View Quoted Comment I think putting it on the details card in the invite is perfectly acceptable, I was just encouraging the original poster to be a little patient and understanding and not feel the need to be rude unless someone disrespects her wishes.

View Quoted Comment You're not wrong. I'm just annoyed by my cousins and their anti-mask propaganda on facebook.

Ahhhh my fault. I misunderstood lol. My apologies. I do agree that there is no need to be rude when not necessary towards guests and I think the first poster worded it nicely. I just meant that I never view wedding websites so I think putting it on there too is not bad but for sure on the invite that masks are required to ensure the safety of everyone in attendance.

View Quoted Comment I think putting it on your wedding website will definitely work, but I’m sure most people who don’t want to wear a mask just won’t show up so I’m sure it’ll be fine. Do you plan on having any sort of other safety reminders for people there? Many people that wear masks don’t wear them properly so will you feel OK with seeing peoples masks below their nose? Also will you be OK with people who may eat with their hands or wiping their nose during dinner time?

I definitely think putting an insert with your invitations is the first step, but you'll need to say it more than once:

In order to protect the health of our friends and family members, we will be taking precautions to prevent the spread of COVID-19. These will include requiring everyone to WEAR A MASK at all times, unless you are eating or drinking. Please do not arrive at our wedding without a mask. See our website for more information.

You can be a little bit more explicit on the website, and also give people a way to reach out to you if they need a mask.
At the beginning of the ceremony, during the, "turn off your phones," announcement, the officiant can remind everyone and give anyone who's not wearing a mask one last chance to get one of the masks you've provided, so you don't have to give them a death stare as you walk down the aisle.

Put on invite and I saw some beautifully cleaver signs on esty

like spread love not germs please wear a mask and a few others.

I would blame it on your venue or something like that so people know it will be enforced. Something like "due to our venue's policies, masks will be required at our ceremony and reception. please reach out to the bride or groom with any questions." and I'd put it on your invites details card and your website.
