1. A functional stretch laminate with a substantially puckered appearance comprising:

  • (a) a first outer layer of a fabric or film perforated with one or more predetermined vias, said first layer defining an inner surface and an outer surface;

    (b) a second outer layer of a fabric or film, said second layer defining an inner surface and an outer surface;

    (c) at least one stretch and recovery element;

    (d) at least one functional element co-extending with the stretch and recovery element sandwiched between the inner surfaces of the outer layers, wherein when the stretch and recovery element is in a relaxed or unstretched state at least one portion of said functional element loops beyond the outer surface of the first outer layer through the one or more predetermined vias in a direction substantially perpendicular to a plane defined by the outer surface of the first outer layer; and

    (e) at least one adhesive composition for bonding the stretch and recovery element and the functional element between the inner surfaces of the outer layers;

    wherein the substantially puckered appearance results when the stretch and recovery element is in a relaxed or unstretched state.
