1. A functional stretch laminate, comprising:

  • (a) a first outer layer of a fabric or film defining an inner surface and an outer surface and a length, and defining two or more perforations therethrough, with each perforation defining a hole opening with a maximum outer dimension;

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

    (c) two or more threadlines of stretch and recovery elements extending along at least a portion of the length of the first outer layer;

    (d) two or more wires, yarns or strands of functional elements substantially parallel to or co-extending with the stretch and recovery elements, said functional elements having a threadline length and having an outer diameter or maximum outer width less than the maximum outer dimension of a corresponding perforation hole opening, with the stretch and recovery elements and functional elements sandwiched between the inner surfaces of the outer layers; and

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

    wherein portions of one functional element are exposed to an environment outside of the laminate through the two or more perforations, and wherein a puckered appearance results when the stretch and recovery elements are in a relaxed or unstretched state.
