Fashion Week is underway in New York City, and American designers are showcasing their visions of the future. I’m watching the proceedings with great interest, but also thinking about celebrated designers of bygone eras, whose works once shimmered on runways.  In this special edition of Let’s Bring Back ..., let’s wind back the clock and spend some time with Paul Poiret, Elsa Schiaparelli, Oleg Cassini, and six other colorful designers of yesterday.
