Yeah I don't know that Mr and Mrs signs are that common anymore. Definitely not a "requirement!" I did not change my name so I spoke to our officiant and DJ to make sure that they didn't announce us as "Mr and Mrs" at the wedding.
We also did the light up letters on our sweetheart table because we liked the look of it. But yeah nothing is a requirement! (Other than a marriage license )
You don't NEED one! It is just a decoration that some couples choose- we won't be having one either!
Some of them are really nice- but they are not a requirement at all
You are already having a wedding that's pretty non traditional so I don't think it matters if you should or shouldn't have the sign! It's your day. You can have it there or not, totally up to you. We are not having a Mr. And Mrs sign. We might put up a sign with a quote or something instead!
I'm not having one. I realized I don't really like the title of mrs for me personally. I think that's my feminist streak although I think it's cute when my FH calls me it. I think people are just excited to be married and be a Mr & Mrs. some of those signs are really cute but you definitely don't need to have one.
