Small ceremony this year and big celebration/renewal next year

At this point I don't think anything is rude lol. If it is due to the COVID restrictions on guest count I think they will understand.

I’d just reach out to each member of the bridal party individually and explain your reasoning, but I think it makes perfect sense to keep your guest count as small as possible.

Like Molly said - these are extraordinary circumstances, so I don't think anyone can really be offended! I think Jessica has a great point though and telling each of your bridal party members individually would be a really nice touch.

My husband is a groomsman in friend's August wedding that has been postponed for TBD in 2021 - they'll also be getting married in a family only ceremony this year and we're not offended in the slightest to not be included! Everyone can only worry about so many priorities and other people right now.

Not at all...I think everyone will be understanding.

I think that your wedding party will be understanding. Most people that are that close to you will just want you to be sane, happy, and healthy.

I don't think this is rude at all. You're trying to make the most responsible choice you can to protect people. Most of them will understand, some may not. But, if it's important to you to keep the group as small as possible in order to prevent covid from spreading, just try to keep that in mind so you don't feel pressured to expand your tiny guest list.

Honestly, it’s not rude but I can assume that it might come off as a slap in the face. I personally wouldn’t invite one and not the rest. But if you are following CDC guidelines then you have to do what is right. Your friends should understand. Maybe a zoom link for the others? Good luck to you!

At this point, I'd include the wedding party because you already asked them, gave them a date, and a lot of them are probably excited about it. Then they can be involved in the next one, too.
