The prices aren't as high as I thought they would be either. I designed a beautiful silk/hemp blend dress for only $750, and it also offers you the ability to save and name your creations which is great for sharing.
Other great shops for environmentally and socially conscious dresses include; Conscious Clothing: a designer offering relaxed summer or beach style hemp dresses in about 10 styles starting at $500, Tara Lynn Bridal: a Etsy designer offering hemp dresses, often embellished with leaves or flowers starting around $1,200, and Rawganique: a clothing store offering a small collection of both simple natural hemp bridal and bridesmaid dresses with a low cost of around $300.
Another option is to consider a recycled wedding gown. You'll find cheaper dresses and helping to preserve natural resources. Recycled Bride offers gently used dresses & donates 15% of their advertising revenue to Global Green USA.
