[5] Her two knitwear clothing lines, Christina Oxenberg and Ox, have appeared in Barneys, Bloomingdale's, and luxury boutiques throughout the world.

She is a daughter of Princess Elizabeth of Yugoslavia (born 1936) and her first husband Howard Oxenberg (1919–2010),[8] a Jewish[9] dress manufacturer and close friend of the Kennedy family.

Through her maternal grandfather Prince Paul of Yugoslavia, of the House of Karađorđević, Christina Oxenberg is also a great-great-great-granddaughter of Karageorge, who started the First Serbian Uprising against the Ottoman Empire in 1804.

Oxenberg's maternal grandmother, Princess Olga, was the daughter of Grand Duchess Elena Vladimirovna of Russia and Prince Nicholas of Greece and Denmark,[13] himself the son of another Romanov grand duchess, Queen Olga Konstantinovna of the Hellenes and her Danish-born husband King George of Greece, brother of Queen Alexandra of the United Kingdom and the Empress Maria Fyodorovna.

[15] In 1994, Simon & Schuster commissioned Oxenberg to write a semi-autobiographical novel that would eventually be published as Royal Blue.

The pair used fibers such as the guanaco from Patagonia, the suri-alpaca from the high Andes and the muskox from the indigenous population in the North West Territories of Canada.

Subsequently, Oxenberg was interviewed by the Sunday Times,[32] Radio Gorgeous[33] and Tatler,[34] and she presented the book at the Oxford Literary Festival on 22 March 2018.

[35] In 2022, she caused a stir with an interview with the New York Post where she discussed the British royals and their long history of hazing newcomers.
