hi camilla,In my world they are! I adore the Matelasse styles (not the new puffy ones from '09 though - i vastly prefer the older '07 type quilting)!
I find quilted bags classic - be it a Chanel or a Balenciaga, so I would say that they never go out of style. I get the sense that the Matelasse never was very popular - at least copmpared to the moto line
