In 1928, a then-unknown Lucille Ball began working for Carnegie as an in-house model. Carnegie ordered Ball to dye her then-brown hair blonde, and Ball complied. Of this time in her life, Ball said, "Hattie taught me how to slouch properly in a $1,000 hand-sewn sequin dress and how to wear a $40,000 sable coat as casually as rabbit." Later, Ball moved back to New York City in 1932 to resume her pursuit of a career as an actress and supported herself by again working for Carnegie and as the Chesterfieldcigarette girl.

On June 1, 1952, Carnegie received the Congressional Medal of Freedom for the WAC uniform design and for her many other charitable and patriotic contributions.
