To wear these pants, simply step into them and zip up the front. They're suitable for casual outings and semi - formal events. For washing, use a gentle cycle in cold water to keep the stretch and color intact. Avoid using bleach as it can damage the fabric. Hang them to dry to prevent shrinking. You can iron them on a low - heat setting if needed. These pants are versatile, so feel free to mix and match with different tops according to your style and the occasion.
