Classy Bachelorette Party

I am planning a bachelorette party for a friend of mine. We are going to do a tour during the day of the local wineries in our area. My friend is not really into the whole veil on her head, lifesaver t-shirt, or tacky sexually explicit toy thing. I am trying to think of something to do so that everyone knows she is the bride-to-be and that it is her special day.

Any suggestions!? Please!
