[2] Born Nettie Rosenscrans in Salzburg, Austria in 1890, she and her family migrated to America in the 1890s and settled in Harlem, New York.

Her clothes were retailed around America, but only one store in each city was permitted to carry fashions bearing Rosenstein's label.

[2] In 1927 Rosenstein tried an early retirement, but resumed designing in 1931, when she reopened on West 47th Street in collaboration with her sister-in-law Eva Rosencrans and Charles Gumprecht.

[4] Whilst these prices were beyond the range of most consumers, Rosenstein's designs were so widely copied that she still influenced the average American woman's wardrobe.

[2][4] Nettie Rosenstein designs also included printed dresses with gloves to match, and she was also known for her accessories and striking costume jewelry.
