Dubbed “Unsinkable” by Brewster for the same reasons Molly Brown was—rising from relatively humble origins to stylish celebrity and then surviving the sinking of the Titanic—Lucy, Lady Duff-Gordon (to use her final married name), not only became a celebrated belle epoque dressmaker in France, Great Britain, and the United States, but is credited with inventing both tinted undergarments to go with her filmier tea dresses and high-society gowns and also runway-style fashion shows with live models. (She also sparked a pre–First World War furor for “Crazy Big Hats.”) Following an isolated glimpse of her as a child living with her strict grandparents near Guelph, Ontario (after her father’s death, the family relocated from England), the author skips ahead through high spots and notable incidents in her career to the Titanic disaster (she and her husband were unjustly stigmatized afterward because of rumors that they had bribed their way aboard a lifeboat), later struggles, and death in 1935. The generous mix of newly colorized period photos and McGaw’s formally composed scenes of shows, dances, and other events offer enough examples of her work to impart a clear idea of their characteristic lines and looks.
