A frient and I recently purchased a "silk" custom made Indian outfits at Shree Carpet & Textile Mahal. When we did the burn test (when we finally werre able to get matches), we found they were pure polyester (petroleum product). I complained to our travel agency, Mercury Travels in Delhi who notified them. The merchant sent back an email saying they had made it clear that the fabric was a mix of cotton and silk (another lie). These outfits are pure polyester and a rip off from an unethical merchant who has not problem putting a lie in writing. DO THE BURN TEST BEFORE YOU PURCHASE ANY FABRIC ITEM IN INDIA. But overall - avoid by anything at Shree Carpet & Textile Mahal.
