First lets clear up a few misconceptions about the luxurious wrap. The name pashmina comes from Pashmineh, made from Persian pashm ("wool"). This wool comes from a special breed of goat indigenous to high altitudes of the Himalayan mountains. And although westerners have adopted the name when refering to the popular wraps, the word itself is intended for the fabric. A wrap containing no pashmina fabric is just a wrap.
Pashmina's in the US are generally plain Jane and come in solid colours with the occassional beading on the fringe. For a really spectacular and authentic pashminas consider checking out Novica.com. An online store dealing in trades from around the world.
