Is it ok to have wedding four months before reception?

It's not tacky at all ! in fact that's what a lot of covid brides do now

Definitely nothing wrong with this, I'd say even before COVID it wasn't unheard of to do this depending on circumstances. But surely with the pandemic going on, no one would think ill of you for having to postpone the reception. And you can do whatever you want with it, have a video of your ceremony at the reception to play during dinner, do a whole ceremony again even or do a vow renewal. The possibilities are endless.

I feel like given the whole COVID thing it is definitely NOT tacky! A lot of brides are choosing to go this route. Either way you choose to do it will be great! And if it's easier and less stressful/ better for your families then yes absolutely wait and celebrate a little bit later with everyone. People will understand especially given the circumstances.

There's nothing tacky at this at all! You could do a unity ceremony or vow renewal for the later celebration, or just jump straight in to the reception!

I think with everything going on there isn't a right or wrong way to do things right now. It's definitely not tacky! I'm having my minimony 10/17/20 and my vow renewal/reception 10/23/21. I will also make sure on my invites for next year to say its for a vow renewal so people know we are already married.
