The 2013 Beijing International Design Week provided yet more evidence of the capital's emergence as a center for independent fashion design. To help kick off the design week, the Beijing-based German designer Kathrin von Rechenberg unveiled her new Fall/Winter Line with a show at the inauguration of "The Cocoon" in the exclusive Hotel Eclat at Parkview Green.

"I'm passionate about tea silk," Rechenberg tells me, as we chat before the show. The Taiwan fashion designer Sophia Hong introduced the Munich-born Rechenberg to tea silk, and this fabric, along with her Chinese husband from Wuhan, brought her to China in 2000.

Rechenberg says: "I buy silk from all over China, but there is only one place, the small city of Daliang in Guangdong, that prepares the fabric in the traditional tea silk way." That preparation involves dyeing the silk up to 40 times in tea and other organic ingredients and, after each dyeing, spreading it out on the grass to dry in the sun. During this process, the silk is covered with mud, giving it a unique papyrus texture. This special sheen also becomes glossier and more lustrous with age.
