To wear these sweatpants, simply pull them on and adjust the drawstring waist to your comfort. They're great for casual outings, lounging at home, or even running errands. When it comes to maintenance, you can machine - wash them in cold water to keep the color and shape intact. Avoid using bleach as it might damage the fabric. Hang them to dry instead of using a dryer to prevent shrinkage. And remember, these sweatpants are versatile, so feel free to pair them with different tops for various looks.
