I love garb--both historic and fantasy.  I've made a few Renwear type things in the past, but in the last year or so I have gotten really into historic costume.  I don't claim to be an expert (far from it, actually); and I don't do too terrible much independent research (i.e.: I'm lazy).  I try to make something that is acceptable to me.  If that means I want to use day-glo pink polyester to make that Elizabethan, then by golly that's what I'm going to do.  Not that I'm all that partial to day-glo pink polyester, mind you.  What I'm trying to say is: don't assume what I do on my stuff is particularly accurate.
