Take a baby shirt that fits your pooch. Take some scrap fabric and pleat, making adorable flounces. Cut the shirt to the place where you would like the bodice to end and the skirt to start. Sew or glue on the ruffles. Hem as needed. You can also just sew a shirt/top by yourself if you have some sewing skills.I love sewing Taffy dresses, and she does not mind wearing them.
