These shirts are super easy to wear. Just slip them on like any other shirt and adjust the belt to your preferred tightness. They're great for casual outings like hanging out with friends or running errands. When it comes to cleaning, you can machine - wash them in cold water with a gentle cycle. Use a mild detergent to keep the fabric in good condition. Avoid using bleach as it might damage the color. After washing, tumble dry on low heat or hang them to dry. Iron them on a low - heat setting if needed. Also, remember that because of manual measurements, there might be a 2cm / 1 inch difference in size, so pick the size that suits you best.
