To use this Kelia shirt, simply put it on like any other shirt. It's great for casual outings or just relaxing at home. As there's a small yellow mark on the back bottom, try not to draw too much attention to that area. When it comes to maintenance, follow the care instructions on the label. Usually, a gentle machine wash in cold water is a good idea. Hang it to dry to keep its shape. Enjoy wearing your unique Kelia shirt!
