LONDON (AP) — The dresses tell the story of a life cut short: first the frilly debutante frocks Princess Diana wore before she married Prince Charles, then the elaborate gowns that stunned the world, and finally the power suits she favored shortly before her death. A new exhibition that opens Friday at Kensington Palace, her home for many years, will give the public a chance to see extraordinary fashion pieces up close for the first time. The workmanship is refined, some of the designs are simple in concept and execution, while others clearly took careful thought and meticulous preparation. Diana was married to Prince Charles, and a guest of President Ronald Reagan and his wife Nancy, but that didn't stop her from tearing up the dance floor with John Travolta at a White House state dinner in 1985. [...] honeymoon photos with Charles taken in the lovely Scottish countryside, Diana turned to designer Bill Pashley for a casual, comfortable brown tweed woolen day-suit. Diana relied heavily on Walker at various times in her life, and she turned to Walker again in the years just before her death to help her refine a "working princess" style in line with her plan to devote more time to charitable activities.
