Invite Wording Question

I think I know the answer to this, but I'll ask anyway. Would the invites say 'bride and groom, together w/ their parents' or bride and groom, together w/ our parents' - I think it's their parents, as if someone else is talking, right? And it would be 'as they exchange vows' as opposed to 'as we exchange vows' right?

TIA

I've seen it both ways but I think it's more formal to say 'together with their parents'
and 'as they exchange vows'

But it's totally up to you.

Bride and Groom together w/ their parents.

As they exchange......
