Occasionally during searches through the second hand shops I find a really nice white or cream jacket. So there may never be a lot of them here, but I'm always on the lookout so check back frequently. I don't bother with anything that isn't good quality and well cut.
Lastly, please note, we are not a big industrial dye house, we are a small backyard setup and as such, we do not achieve perfect results. Sometimes blue gets where it shouldn't and sometimes the large areas of blue are not all one perfect shade. We do not "fix" them by adding colour or bleaching it away when it gets where it shouldn't. What comes out of the vat is what you get. We use natural indigo, not synthetic and try to use organics instead of strong chemicals at every stage.
