I hope it is ok to put this here.
I volunteer/work at Philip Foster Farm, a historic site on the Oregon trail (specifically, the Barlow road near Mt. Hood). Every year we have a garden party and fashion show, and it falls to me (who usually just works on costumes and talking to tours) to arrange for a nice talk about the fashions of the time.
The participants in the show are volunteers who already have an authentic outfit, and some knowledge to go with it. The MC is yet to be determined this year, but in previous years I have gotten Marge Harding or Kay Demlow to come. The MC describes each outfit for our little crowd, and gives some history with it. However, a big part of the fun is the time before and after the show, getting to talk with the guests, and show them the stories and work that go into all the clothing we are showing. Some of the participants have even stayed in a first person impression for that time, which was really cool. I don't have a theme this year, so we are just looking around for people with any sort of impression from anywhere in that 1800-1900 range.
Personally, I also enjoy getting to see the historic site in full swing. We get our blacksmith shop going, and our cookstove, and our store. This is sort of a shameless plug, but it really is one of my favorite places, and the event is one of my favorite events.
If you are interested in volunteering, the day is July 16th, and the event runs 1pm-4pm. The fashion show only goes on for maybe 30 minutes of the event, but it is still a good idea to come at 12 or 12:30 to get a bit of an orientation. To sign up,you can email me at firstname.lastname@example.org
To see a bit of what it is, check our website (note, this is an event from a while ago, and the participants you see were actually models wearing clothes from a collection, so though the form of the event is similar the elements are different): http://www.philipfosterfarm.com/pffwp/mary-charlottes-garden-party/
