To use these briefs, simply put them on like you would any other pair of underwear. The high - waist design should sit comfortably around your waist. When it comes to washing, use a gentle cycle in cold water and air - dry them to keep the cutout details and the seamless texture in good condition. Avoid using harsh detergents as they may damage the fabric. Also, don't wring them out forcefully after washing to prevent any stretching.
