Every girl needs a lil black dress in her wardrobe. Our new Lil Black Sweater Dress with a hand crocheted flower at the neck will make a fashion statement that will be the dog's bow wow! They are 100% acrylic and come in sizes 6"-16". Machine washable. To determine size, measure from the base of the neck to the base of the tail. For dogs with a little more weight or fluff, go up a size.
