Saris/Indian Clothing and Sewing Patterns
Saris were used for both Inara's outfits and Kaylee's big floofy 'Shindig' dress. Dspin says, "The best/most helpful/most reliable sari site I have ever found is actually www.sarisafari.com. Melinda's saris are beautiful, almost all natural fiber and many of them are hand woven. She is also domestic, so the shipping is fast."
