Check on ebay they have one store on there that sells clothing at a good price. I am a big woman size 3x and just bought a dress for 60. with shipping and all.
Check out some pics from different Renaissance Faire's websites too & get an idea of the look you want. You can find stuff at thrift stores easily (or maybe even your own closet!)- longish flowing skirts in tweeds/plaids patterns, etc; 'peasant' blouses (good if you go for a pirate look too!); button-up or lace vest/bodice for over the blouse; flat mary-janes, etc... My boyfriend & I dress up for pirate/ren faire stuff & that's how we get all our stuff.
