To wear this Otis Dress, simply slip it on over your head. It's a great addition to your wardrobe for casual outings or special events. As there's a small grey mark under the left bust, try not to focus on it. When it comes to maintenance, follow the care instructions on the label. Usually, a gentle machine wash in cold water should do the trick. Avoid harsh detergents as they might damage the fabric. Enjoy wearing your unique dress!
