A method of making an undergarment having refastenable side seams (12, 14). The method includes a step of preconditioning a substantially two-dimension web (57) to include at least four refastening surfaces (82-85). The refastenable side seams (12, 14) can be incorporated into undergarments formed from a continuous web (57) in which the pre-forms (21) (that will ultimately result in individual undergarments) are oriented in either the machine direction or the cross-direction. The web (57) can be preconditioned to include refastening surfaces (82-85) on both of what becomes the exterior surface (30) and the body-contacting surface (28) of the undergarments.
