Looks like these might be M? Hey, I love these and I'd snap them up if they are slightly durable....I can't tell if these are just a very sheer fabric with a lace pattern on it, or if they are basically lace ( which for whatever reason tend to get torn up in my washing machine or I put a finger thru it by accident). Can you give a little more description or perhaps a closer up photo of the material? Thanks so much
