How to address people who assume they have a plus one

While you don't have to extend plus 1's to every single guest, you should do so for your bridal party as a sign of respect. These are the people nearest and dearest to you, wouldn't you want to make it as enjoyable for them as possible?

Also, what exactly do you deem to be a "serious relationship"? Please make sure that anyone in a relationship (regardless of whether or not you consider it serious) gets invited as a social unit.

I've always seen invites addressed (outer envelope) to 'Mr. and Mrs. Blank' and then inner envelopes addressed to 'Jim and Jane Blank.'

Or if the invite is for a single person who is allowed a guest, the outer is addressed to 'Mr. Jones' and the inner is 'Jay Jones and Guest.'

Is it really that difficult for guests to understand this concept? That the invited individuas will be named and number of guests indicated? Why leave the response card so open-ended? I intend to have my response card wording 'X number of seats are reserved for you. Please initial entree choice.' I feel like as long as the wording is polite and guest number specific, people shouldn't get too butthurt when they aren't allowed a plus one.

(I say this now, but when I start receiving my invites back in a few months and they're all over the place, I'll be pulling my hair out too.)

You really should invite people's significant others if you can. Plus ones are a different story if the person is truly single, but if they are in a relationship their SO should be invited. As long as you are doing this, I think you are good!!

Id say let the bm have a plus one, and if you're against others who arent in a solid relationship having a plus one....just spray them with a water bottle and say no! bad!!....or is that with cats? lol

I am one of those people who think it is RUDE to not give your guest a plus 1, no matter if they have dated a month or 10,000 years. Some people do become serious and get married early on. How would you feel if your FI got an invite to a wedding and you were not invited because the bride/groom didn't think you were that serious. When you were initially setting your guest list and budget, you should have planned/ fit into your budget for plus 1's. Does nobody care about etiquette around here? You know, it exists for a reason.

You can put on your invitation "(blank) seats have been reserved in your honor." then just write In the number. Thats what we are doing to make it super clear how many plates we will have for their party.
