         2 . The absorbent article of  claim 1 , wherein the second plurality of elastics comprise curved elastics and straight elastics, the straight elastics being parallel to a lateral centerline on the center chassis. 
     
     
         3 . The absorbent article of  claim 1 , wherein the absorbent article comprises a front inner belt portion disposed in the front waist region and a third plurality of elastics disposed in the front inner belt portion and inward of the front outer belt portion. 
     
     
         4 . The absorbent article of  claim 3 , wherein the absorbent article comprises a fourth plurality of elastics disposed in the front outer belt portion. 
     
     
         5 . The absorbent article of  claim 1 , wherein at least one of the front waist edge and the back waist edge is curved. 
     
     
         6 . An absorbent article having a center chassis, the center chassis comprising a topsheet, a backsheet and an absorbent core, the absorbent article comprising:
 a front waist region and a front waist edge;   a back waist region and a back waist edge;   a front inner belt portion disposed in the front waist region;   a front outer belt portion disposed in the front waist region,;   a back inner belt portion disposed in the back waist region;   a back outer belt portion disposed in the back waist region, wherein at least one longitudinally opposing edge of the back outer belt portion is permanently bonded by a side seam and at least one leg opening is preformed;   a first plurality of elastics disposed in the front inner belt portion and inward of the front outer belt portion a second plurality of elastics disposed in the front outer belt portion and outward of the front inner belt portion;   a third plurality of elastics disposed in the back inner belt portion and inward of the back outer belt portion; and   a fourth plurality of elastics disposed in the back outer belt portion and outward of the back inner belt portion;   an outer belt layer is disposed in the back waist region, wherein the outer belt layer is selected from a group consisting of a nonwoven, a film, and a laminate that includes a nonwoven and a film; and the outer belt layer separates the third plurality of elastics from the fourth plurality of elastics;   wherein at least a portion of at least one of the first, second, third and fourth plurality of elastics comprise curved elastics and straight elastics, the straight elastics being parallel to a lateral centerline on the center chassis;   wherein at least a portion of at least one of the first, second, third and fourth pluralities of elastics comprise anchoring elastics;   wherein at least a portion of at least one of the first, second, third and fourth pluralities of elastics comprise shaping elastics; and   wherein the absorbent article is disposable and wearable and wherein the front and back inner belt portions and the front and back outer belt portions are disposed outward of the backsheet.   
     
     
         7 . The absorbent article of  claim 6 , wherein both longitudinally opposing edges of the back outer belt portion are permanently bonded by a side seam and two leg openings are preformed. 
     
     
         8 . The absorbent article of  claim 6 , wherein at least a portion of the anchoring elastics overlie the side seam. 
     
     
         9 . The absorbent article of  claim 6 , wherein at least a portion of the anchoring elastics overlie the absorbent core. 
     
     
         10 . An absorbent article having a center chassis, the center chassis comprising a topsheet, a backsheet and an absorbent core, the absorbent article comprising:
 a front waist region and a front waist edge;   a back waist region and a back waist edge;   a front inner belt portion disposed in the front waist region;   a front outer belt portion disposed in the front waist region,;   a back inner belt portion disposed in the back waist region;   a back outer belt portion disposed in the back waist region,   a first plurality of elastics disposed in the front inner belt portion and inward of the front outer belt portion   a second plurality of elastics disposed in the front outer belt portion and outward of the front inner belt portion;   a third plurality of elastics disposed in the back inner belt portion and inward of the back outer belt portion; and   a fourth plurality of elastics disposed in the back outer belt portion and outward of the back inner belt portion;   an outer belt layer is disposed in one of the front and the back waist region and is the outermost layer of one of the front outer belt portion and the back outer belt portion, wherein the outer belt layer is selected from a group consisting of a nonwoven, a film, and a laminate that includes a nonwoven and a film; and the inner belt layer separates the first plurality of elastics from the second plurality of elastics;   a fastener in one or both of the front waist region and the back waist region;   wherein at least a portion of at least one of the first, second, third and fourth plurality of elastics comprise curved elastics and straight elastics, the straight elastics being parallel to a lateral centerline on the center chassis;   wherein at least a portion of at least one of the first, second, third and fourth pluralities of elastics comprise anchoring elastics, and at least portion of the anchoring elastics overlie the fastener;   wherein at least a portion of at least one of the first, second, third and fourth pluralities of elastics comprise shaping elastics; and   wherein the absorbent article is disposable and wearable and wherein the front and back inner belt portions and the front and back outer belt portions are disposed outward of the backsheet.
