To wear this Billy Dress, simply zip it up from the back. It's a great piece for casual outings or semi - formal events. As there's a grey mark on the back near the zip, try to style it in a way that this mark isn't very noticeable. When it comes to maintenance, follow the washing instructions on the label. Usually, a gentle machine wash in cold water is recommended. Avoid using harsh detergents that might damage the fabric. Hang it to dry instead of using a dryer to keep its shape intact. Enjoy wearing your unique Billy Dress!
