Hi I'm struggling to find decent dress fabric online. I used to get some from John Lewis or Fenwicks when I lived in Newcastle, but now I'm in the wilds of North Yorkshire . I've found Boyes department stores sell ok craft fabric, but looking specifically for dress fabric. I have my eye on making a stretch shift dress with elbow length sleeves so need a fine stretch wool, wool mix or even polyester crepe fabric.
I have the same problem of not having a fabric shop around the corner. I'm not too partial to buying fabric online (you can't see or touch it!), but I've used these two suppliers on ebay and they are really good - fantastic quality too:
