To use these slippers, simply slip your feet in. They fit true to size, so pick your regular size. When wearing, you can pair them with your favorite evening dresses for a glamorous look. As for maintenance, keep them away from water to prevent damage to the satin and marabou. If they get dirty, use a soft brush to gently remove dust. Store them in a cool, dry place, preferably in a shoe box, to keep their shape.
