These Retro Blue Loose Patchwork Jeans are super easy to wear. Just put them on like any other pair of jeans, and you're ready to go. You can pair them with a simple T - shirt for a casual look or dress them up with a nice blouse. When it comes to washing, turn them inside out and use a gentle cycle in cold water. This helps to protect the patchwork and the color. Avoid using harsh detergents as they may damage the fabric. After washing, it's best to air - dry them to maintain their shape. As for sizing, always check the size chart carefully because different suppliers and brands may have variations. If you're in between sizes, it's usually better to go for the larger size for a more comfortable fit, especially since these are loose - fitting jeans.
