To use these panties, simply put them on like you would any other underwear. When it comes to care, it's best to wash them in cold water with mild detergent. Avoid using bleach as it can damage the lace. Hang them to dry instead of putting them in the dryer to keep their shape. Remember, these panties are for daily wear and are not suitable for any strenuous physical activities. Enjoy the comfort and shaping they provide!
