Somewhere in there mention if you're having dinner and dancing or just desserts.

You could word the invitation as "a celebration of [name] & [name]'s marriage" or "a reception celebrating [name] & [name]'s [wedding_date] wedding".

Call it whatever you want: there are some etiquette cops here who will tell you it isn’t a “wedding” if you are already legally married. A wedding is when you celebrate the union with your friends and family. These are crappy situations and anyone who gets mad over wording on an invite can uninvite themselves.

View Quoted Comment I completely agree with this - you can word the invitations however you want! I interpreted your original question as you wanting to reference your July ceremony in your invitations for your September event, so my earlier suggestions were based on that. Find whichever wording you like best (a wedding, a vow renewal, a celebration, a reception, etc.), and go for it!
