In order for our wedding to be perfect, we must plan everything completely/down to the last detail.



Do both of the above versions equally idiomatic? Which one is more often used? Thanks.

I think they are equivalent. I suppose it depends on where you are in the country but I think "down to the last detail" is more descriptive and more common.

Thanks, Carl.

Got it!
