Various garments are disclosed which include a body adhesive for attaching the garment to the skin of a wearer. More particularly, the garment can include at least one extensible portion. An adhesive member comprising an adhesive layer and a cover member may be positioned over the extensible portion. The cover member may completely cover the adhesive layer when the extensible portion is in a relaxed condition. When the extensible portion is stretched, however, the cover member may define openings that expose the adhesive layer for adhering the adhesive to a wearer. The garment may comprise, for instance, a diaper, a training pant, a swim pant, a hospital gown, an industrial garment, a glove, a feminine hygiene product, an adult incontinence product, and the like. The adhesive member can be positioned over any suitable extensible portion on the garment.

1. A garment comprising: a chassis having a shape configured to surround a portion of a wearer's body, the chassis including a front portion and a back portion and an inner surface that is placed adjacent to the wearer's body and an outer surface wherein the chassis defines at least a front inner surface and a back inner surface;an extensible portion that permits the chassis to expand in an area for providing the chassis with a form fitting property around a portion of a wearer's body;an adhesive member positioned on the back inner surface of the chassis and over the extensible portion, the adhesive member including an adhesive layer applied over the extensible portion and a cover member wherein the cover member is adjacent to the wearer's skin, the cover member substantially covering the adhesive layer and wherein, when the extensible portion is stretched in a lateral direction, the cover member defines openings facing the wearer's skin that expose the adhesive layer to the wearer's body; andwherein the adhesive layer of the adhesive member has low tack and a peel strength of no more than about 140 grams per centimeter of width and is configured to provide a cyclic shear value of no more than about 100 cycles, such that the adhesive will detach during use from the wearer's body after initial application. 2. A garment as defined in claim 1, wherein the garment comprises an absorbent article that includes an outer cover, an absorbent core, and a liner, the absorbent core being positioned between the outer cover and the liner, the liner defining the inner surface. 3. A garment as defined in claim 2, wherein the absorbent article, when positioned on a wearer's body, includes first and second leg openings and a waist opening, the extensible portion surrounding the waist opening. 4. A garment as defined in claim 2, wherein the absorbent article, when positioned on a wearer's body, includes first and second leg openings and a waist opening, the extensible portion is positioned around at least one of the leg openings. 5. A garment as defined in claim 2, wherein the absorbent article comprises a feminine care pad. 6. A garment as defined in claim 1, wherein the extensible portion comprises a cuff. 7. A garment as defined in claim 1, wherein the extensible portion comprises an elastic laminate. 8. A garment as defined in claim 7, wherein the elastic laminate comprises a stretch bonded laminate. 9. A garment as defined in claim 1, wherein the cover member comprises a nonwoven web. 10. A garment as defined in claim 1, wherein the cover member comprises a spunbond web. 11. A garment as defined in claim 1, wherein the cover member defines a plurality of apertures or slits that define the openings when the extensible portion is stretched. 12. A garment as defined in claim 11, wherein the cover member has a length that is generally parallel with the apertures or slits, the apertures or slits only extending over a portion of the length, the slits having a length from about 3 mm to about 12 mm. 13. A garment as defined in claim 12, wherein the apertures or slits are spaced apart a distance of from about 3 mm to about 10 mm. 14. A garment as defined in claim 11, wherein the apertures or slits have a length that is from about 20 percent to about 80 percent of the height of the cover member. 15. A garment as defined in claim 11, wherein, when the extensible portion undergoes a 30 percent elongation, the apertures or slits form the openings that have a total surface area of from about 5 to about 100 mm2. 16. A garment as defined in claim 11, wherein the slits or apertures are arranged in columns over the cover member, each column containing a plurality of apertures or slits. 17. A garment as defined in claim 1, wherein the extensible portion comprises an elastic film upon which the adhesive layer is disposed. 18. A garment as defined in claim 1, wherein the adhesive layer of the adhesive member comprises a silicone, an acrylic, a polyurethane, a polyester, a polyamide, a styrene butadiene, a polyisobutylene, a polybuadiene, a polyisoprene, a polyvinyl alcohol, a polyvinyl acetate, a methyl cellulose, a styrene-butadiene-styrene, a styrene-isoprene-styrene, a styrene-ethylenepropylene-styrene, a styrene-ethylenepropylene-styrene-ethylenepropylene, a styrene-ethylene butylene-styrene, or mixtures thereof. 19. A garment as defined in claim 1, wherein the adhesive layer of the adhesive member defines a shear storage modulus of from about 1.0 ×103 to about 6.0×106 dynes per square centimeter as measured at a temperature of 20° C. and at a frequency of 10 radians per second. 20. A garment as defined in claim 1, wherein the adhesive layer of the adhesive member is configured to provide an initial shear strength of no more than about 600 grams per square centimeter. 21. A garment as defined in claim 1, wherein the adhesive layer of the adhesive member is configured to provide an aged shear strength of no more than about 500 grams per square centimeter. 22. A garment as defined in claim 1, wherein the adhesive layer comprises a plurality of discrete adhesive areas, the adhesive areas being position only beneath the openings defined by the cover member. 23. A garment as defined in claim 1, wherein the adhesive member is positioned on a flap positioned on the back inner surface of the chassis and over the extensible portion such that when the extensible portion is stretched in a lateral direction, the cover member on the flap defines openings facing the wearer's skin that expose the adhesive layer to the wearer's body.
