I was excited to get this rag & bone jacket at a discount. But it's stiff and even though it's supposed to be dry clean only and I've washed it several times and put in the dryer, it remains pretty stiff. I'm beginning to think it was a mistake and I would have been happier with a cheaper stretch denim jacket. Will any amount of washing and drying soften this thing? I think I tried a vinegar soak. Today I saw something that said put salt in the water. I know my DH's old denim jacket got very soft but that was after years of washing and wearing.
