• a first elastic extension and a second elastic extension each constructed of at least about 75% polyester, at least about 3% spandex, and at least about 15% nylon, each of said first and second elastic extensions having a proximal end and a distal end, said first elastic extension ultrasonically bonded at said proximal end to said first side of said main body and said second elastic extension ultrasonically bonded at said proximal end to said second side of said main body, and each of said first and second elastic extensions extending from said top edge of said rear portion toward said crotch portion;
• and a first attachment area and a second attachment area each having a plurality of engaging elements, each of said first and second attachment areas secured to said liquid permeable top sheet and each extending longitudinally from said top edge of said front portion toward said crotch portion, and said plurality of engaging elements on said first attachment area engaging with said first elastic extension and said plurality of engaging elements on said second attachment area engaging with said second elastic extension to secure said disposable undergarment at least about 0.5 inches below said wearer's waist;
• b) holding said rear portion of said disposable undergarment against said wearer's buttock and below said waist, and wrapping said front portion around said crotch portion of said wearer's body;
• c) stretching said first elastic extension around one of said wearer's hips and securing said first elastic extension to said plurality of engaging elements formed on said first attachment area;
• and
• d) stretching said second elastic extension around said wearer's other hip and securing said second elastic extension to said plurality of engaging elements formed on said second attachment area such that said disposable undergarment is secured to said wearer's body below the waist.

A method of removing a soiled disposable undergarment from around a crotch portion of a wearer's body, said wearer's body having a buttock and hips, said method comprising the steps of:

• a) utilizing a disposable undergarment which includes a main body having a longitudinal central axis, an absorbent core aligned along said longitudinal central axis, a first side and a second side, each of said first and second sides being located laterally outboard of said absorbent core, said main body having a liquid permeable top sheet which contacts a wearer's body and a liquid-impermeable back sheet, formed from polypropylene, spaced away from said wearer's body, said main body having a front portion, a rear portion, and a crotch portion located between said front and rear portions, and each of said front and rear portions having a top edge;
• a first elastic extension and a second elastic extension each constructed of at least about 75% polyester, at least about 3% spandex, and at least about 15% nylon, each of said first and second elastic extensions having a proximal end and a distal end, said first elastic extension ultrasonically bonded at said proximal end to said first side of said main body and said second elastic extension ultrasonically bonded at said proximal end to said second side of said main body, and each of said first and second elastic extensions extending from said top edge of said rear portion toward said crotch portion;
• and a first attachment area and a second attachment area each having a plurality of engaging elements, each of said first and second attachment areas secured to said liquid permeable top sheet and each extending longitudinally from said top edge of said front portion toward said crotch portion, and said plurality of engaging elements on said first attachment area engaging with said first elastic extension and said plurality of engaging elements on said second attachment area engaging with said second elastic extension to secure said disposable undergarment at least about 0.5 inches below said wearer's waist;
• b) releasing said first and second elastic extensions from said plurality of engaging elements formed on said first and second attachment areas;
• c) moving said disposable undergarment away from said wearer's body whereby said wearer's hips and buttock are no longer contacted by said disposable undergarment;
