Garden Party or Dinner Party?

[LovelyEsq]

So I am throwing an engagement party for my sister and I am trying to word the invitations. It will be outdoors in a big backyard with a swimming pool. I want to know if I should call it a "dinner party" or a "garden party" on the invitations? A full menu will be served...

Garden party, but definitely enclose that there will be a full menu for dinner.
