Pinning this image from the Vapor Thrift Store in Jackson, California. Their description:
Looking for costume ideas? Meet Princess Autumn, our window mannequin. We've had at least five customers wanting to buy her dress. With a little creative ingenuity and a few thrift store purchases (an old wedding dress, two satin flat sheets, one plaid tablecloth, one green shower curtain, one valance, yards and yards of inexpensive orange fabric lining, one sheer curtain, an orange scarf, a satin purse and an armful of dried fall flowers), you too could be an Autumn Princess, or anything else for that matter.
