These white Ellira pants are super easy to wear. Just slip them on like you would with any regular pants. As for the yellow elastic on the right side of the waist, it adds a cool touch and also helps keep the pants in place. Remember, these are a one - off sample, so they're extra special. When it comes to maintenance, you can machine - wash them on a gentle cycle with cold water. Hang them to dry to keep the color and shape. And since they can't be returned, take good care of them so you can enjoy wearing them for a long time.
