This beautiful dress is apparently made from hand-loomed shimsa (nonviolent) silk blessed by H.H. The Dalai Lama, hand-dyed with iris root, sumac leaves, boiled carob, indigo, blueberries, first-year woad leaves, mulberries, elderberries, grapes, cherry root, red maple, raspberries, blackberries,
pokeweed, hibiscus, day lillies, and (wait for it)
logwood!.
