Lame incorporates metallic threads alone or alongside other yarns. Sewport describes both genuine and imitation varieties used for costumes, formal clothing and decorative textiles. The metal-containing element creates the distinctive reflection, while natural or synthetic companion fibres contribute other aspects of the fabric.

That is why a reflective appearance does not establish one degree of stretch or stiffness. The thread combination and construction determine whether the finished textile moves fluidly, holds shape or behaves more elastically.
