 Each season fashion designers desperately search for the next big thing. In many cases, they turn to the past for inspiration -- Greta Garbo, Joan Crawford, Doloris Del Rio, Claudette Colbert, Audrey Hepburn, Marlena Dietrich -- their legacies still haunt the runways. Everything we wear is grounded in a bit of history. But you can t wear history or can you? Take a walk with us down Madison Avenue and count the pairs of Jackie O  sunglasses, bellbottom pants and polyester pullovers. Tune into the "Today Show" to get a glimpse of Katie Couric s flashback-to-the- 50s in those classic twinsets. From the street to the boardroom, simply take a look around today s fashion is a modern bent on an old fashioned standard.
