Abstract: A garment has an automatically-adjustable-length drawstring with readily-flexible ends that can be tied to enable the garment to accommodate a large number of waist sizes; and that drawstring will automatically expand as the circumference of the wearer's waist increases during breathing in or movement of the wearer's body, and that drawstring will automatically contract as the circumference of the wearer's waist subsequently decreases during breathing out or movement of the wearer's body. In doing so, that drawstring will hold the waist of that garment against drooping relative to a user's waist. A resilient, extensible section between the readily-flexible ends of the drawstring will automatically and continuously maintain an effective, but lower-than-normal, value of frictional force between the waist of the garment and a wearer's waist.
