As far as costume and character at a RenFaire goes, there are a couple of
different options, ranging from peasant to "middle class" to noble lady.
Since the venue is outdoors, and the weather (depending on your location)
may be variable, and include rain, most of the costumes I've seen (and my own
as well) tend toward the lower end of the socioeconomic scale, as these are
easier to wash and maintain. My wife has elaborate Renaissance garb for
events with the Society for Creative Anachronisms, but she seldom, if ever,
uses it at the RenFaire, as such garb can be very uncomfortable, especially
in 90 degree temperatures and 90 percent humidity. Also, peasant type garb
is easier to make or buy.
If I were you, I would pick a character type that you like and stick with it.
If you like, you can even pick music to match. For several years, my wife
and I would alternate between English (more or less) middle class garb
singing English songs, and Scottish garb and doing mostly Scottish songs. If
this is your first time, and if you are not used to performing, then stick
with the music you are most comfortable with, and pick the easiest costume to
perform in consistent with both your music and your comfort.
Remember, Renaissance Faires are commerical enterprises intended to entertain
the public. I mean them no disservice when I say that, but what it does mean
is that you have some leeway in terms of authenticity. If you are playing
typical Celtic music, your music is not, strictly speaking, Renaissance
music. But, at at RenFaire, your audience (with rare exceptions) won't care,
your faire management won't care, so don't worry about it. What you want to
avoid are obvious and blatant modern dress and songs (halter tops, for
example, or singing "Johnson's Motor Car").
I'm been fortunate enough to have a lot of good experiences playing at
RenFaires. There is a lot of opportunity for one-on-one audience contact, and
generally nobody is too critical. For me, Renfaires are an ideal low-pressure
gig, and I'm sure you will enjoy yours.
Best of luck!
