The waistband portion has a relaxed circumference wherein between about 45% to about 70% of the circumference is defined by the elastomeric portion. The waistband portion has an extended circumference for a target wearer wherein, at the extended circumference, the elastomeric portion is extended between about 10% to about 40% of its relaxed circumferential length.
