Ricamo Rete a treatment where leather is stretched over a metal mesh framework. I believe this is S/S 2013.
Also from the look of the clutch, there must be some vacuum treatment, don't you think?.. to get the leather to conform around the metal.
Shown in the Nero Ricamo Rete Knot ($1,380) and Ricamo Rete Clutch ($1,480) from Barney's, then the Poussin Knot and Krim Clutch from NM:
