In the 1980s, Carolyne Roehm's life was as close as anyone could come to one of the socialites in Tom Wolfe's Bonfire of the Vanities. Her second husband was Henry Kravis, a private-equity scion known for his leveraged buyout of Nabisco, and they lived in a $5.5 million Park Avenue apartment, furnished with Louis XV furniture and paintings by Renoir and Sargent. She had her own career, too; she had been an assistant, model, and muse to Oscar de la Renta, then left to found her own line.
