Tamara and Tadeusz were divorced (against the artist's wishes) and the portrait she had begun to paint of her husband (cat.38) was never finished. She made the acquaintance of Dr Pierre Boucard, who commissioned several portraits. Working increasingly hard, she began to enjoy financial success, spending long periods in Cannes.

In 1916, in Petrograd (St. Petersburg), Tamara Gorska married Count Tadeusz Lempitzki (or Lempicki, since the nobiliary particle was added later, in France). After jointly emigrating to France with their daughter Kizette, the couple divorced in 1928.

Mabel Bonney (Syracuse, New York State, 1894 - Paris, 1978) was American by birth. Upon her arrival in Paris in 1919, she adopted the name Thérèse and began a career in journalism. In 1921, she received a "decoration for services rendered to education within the framework of university-level exchanges between France and the United States." In 1924, she began doing photographs of artists, writers, and actors. Through her friendship with the fashion designer Madeleine Vionnet, she also became interested in the world of fashion. Later, she would devote herself to reportages on social conditions.

These were the years of Lempicka's greatest success. The museum of Nantes acquired her "Kizette in Pink" (B.81), and a number of rich collectors commissioned portraits - their own, of course, but also that of a wife and daughter for one, or of a mistress, for the other. At the peak of her talent, Lempicka was able to make the most of her feminine models, enhancing their charms with signs of the new spirit of the times. She thus imbued them with elegance and supreme nonchalance, sensuality and throbbing vitality. The portraits - and even the still lifes - belonging to this period convey contagious optimism in a triumphantly youthful and modernist vein. Success lent Lempicka wings, encouraging her to work and exhibit tirelessly. By now, she had found a certain signature style: a highly original, and effective, synthesis of Mannerism and toned down Neo-Cubism. This style was so well matched to the era that, in retrospect, it can be termed as emblematic of it.
