How to Distinguish Real Silk

 Whether you sport a skinny silk tie or a chic silk blouse, natural silk possesses a timelessly luxurious quality. Synthetic materials, such as polyester, provide an alternative that comes at a fraction of the manufacturing cost and doesn't require a single silkworm to make -- sometimes, however, these synthetics get a little sneaky.
