This is a SUNVALLEY Sun Valley ruffled sleeve blouse, available at stores like Naturan. I purchased it and wore it once. It's in relatively good condition. The sleeves have ruffles, and the color is navy, like indigo denim. It can be worn as an inner layer with overalls, showing off the sleeves, or worn alone with wide pants!
