To wear this dress, just put it on like any regular shirt dress and adjust the belt to your preferred tightness. You can wear it on casual outings like picnics or beach walks. For maintenance, it's best to wash it in cold water with a gentle detergent. Hang it to dry to keep the linen fabric in good shape. Avoid using bleach as it can damage the fabric and fade the colors. And when you're not wearing it, store it in a cool, dry place to prevent wrinkles and mildew.
