I have a 1950s Henri Bendel polished cotton (I think this is the fabric type) dress with a novelty print. This is a dress I'm keeping, it's my favorite dress ever, and I would like to be able to wash it. But if it seems like a bad idea to any of you vintage laundry mavens I will dry clean it. Here's a pic so you can see the print and the texture of the fabric. Thank you for any advice!
