To wear these pants, simply put them on like you would any regular pair of pants. For a casual look, you can pair them with a T - shirt and sneakers. For a more formal occasion, go for a shirt and heels. When it comes to washing, use a gentle cycle with cold water to keep the color and stretch intact. Avoid using bleach as it may damage the fabric. After washing, hang them to dry to prevent shrinking. Iron on a low - heat setting if needed to keep them looking fresh.
