Tea Party Anyone??

I actually took this photo last summer while I was cruising estate sales, but lately I have been thinking about having a tea party... We used to have them when I was little at my moms house (she has quite the collection of tea cups and plates herself) and when I brought it up to her she thought it was a great idea! I know I want pretty dresses and hats to be involved, but I am not sure what else. Any ideas??
