documents: #Person1#: Frank, I want your advice on something. Some scientists I met at the conference 6 this afternoon have invited me to a party. Actually, they called it an informal get-together.
  #Person2#: And what's the problem?
  #Person1#: When I asked how people were going to dress, Dr. Lite said it was casual.
  #Person2#: And you want to know what to wear?
  #Person1#: Well, last night I went out with some journalists for a casual party, but I was overdressed. I wore what I consider casual - - an outfit of skirt, blouse, scarf, and medium heels. . . you know.
  #Person2#: That sounds just right to me. What was wrong with it?
  #Person1#: Everyone else there was wearing blue jeans. Several of the women had on running shoes. I felt out of place. So I have no idea what to wear tonight.
  #Person2#: My guess is you can safely wear last night's outfit to tonight's party.
