Background: We didn't want to begin our married life in debt so we chose the City Hall route. Trust me, I'm not the pretty princess bride type either.
We got married at City Hall in Manhattan with our immediate family present then went out to a wonderful dinner afterwards. It was perfect and I would never have it any other way. Going into it, we planned to have a party with our friends and extended family a year later. We're not looking for gifts and we're not looking to re-enact the wedding (no ceremony, speeches, etc). We just want to celebrate with our friends and family because we couldn't afford to host a wedding reception when we got married. (We're paying for everything ourselves - no parents help).
Question: What would you call this party on the invitation? Most of our friends and family already know we're married. We want people to know we're celebrating our marriage. We're aiming for an outdoors, casual, backyard, romantic dinner style party.
