To use this shirt, simply put it on like any regular shirt. It's great for casual outings or can be dressed up a bit. When it comes to sun protection, it works best when worn under direct sunlight. For maintenance, machine wash it in cold water with similar colors. Avoid using bleach as it can damage the fabric. Tumble dry on low to keep its shape and stretch. If you notice any stains, spot - clean them gently before washing. Also, store it in a cool, dry place to keep it in good condition.
