I have bought a couple of 100% silk blouses for work in the LK Bennett sale, but they say dry clean only. I have hand washed silk in the past and it has been fine. Do they say this just to cover themselves if anything happens? Is it worth the risk. They were vastly reduced but still not cheap so don't want to wreck them but I can see I will end up spending more on dry cleaning than on the cost of the blouses themselves. If I were to hand wash them how is it best to do it, cold water?
