Those are lovely dresses. I, personally, probably wouldn't, as I make most of my pieces myself. If I had the money and lacked the sewing skills, I would so be buying stuff off of e-bay.
Part of it depends, though. A lot of people who don't sew aren't looking for the more expensive high-quality stuff. Many people who buy things online are looking for things to be cheap. So it all really depends on your marketing.
I agree, if I lacked sewing skills, I'd SO buy one of those pretty dresses for the Ren. Faire!
