These multi - pocket casual patchwork pants are super easy to use. Just put them on like you would any regular pair of pants. You can use the multiple pockets to store your phone, keys, wallet, or other small items. When it comes to washing, you can toss them in the washing machine on a gentle cycle with cold water. Use a mild detergent to keep the fabric and colors in good condition. Avoid using bleach as it may damage the cotton and the patchwork design. After washing, hang them to dry to prevent shrinking. Remember to check the size chart before buying as different suppliers and brands may have different sizing. If you usually wear a certain size in US sizing, you might need to choose a different size in Asian sizing, as shown in the size chart example.
