Any stores/websites featuring hippie/natural/free-flowing wedding dresses?

I'm not talking about those uber-hippie wedding dresses that feature patchwork quilting or pictures of rabbits sharing a carrot under a tree. I just mean flowing, casual, natural wedding dresses (or just white dresses....doesn't need the "wedding" title) that aren't all poof or glitz. Any suggestions for websites? And please, no Davids Bridal or Alfred Angelo, etc. Thanks!!
