Since skyrocketing to fame in 2003 as Paris Hilton’s best friend on the Fox surprise-smash series “The Simple Life,” Nicole Richie has become one of Hollywood’s most prominent fashion icons. Richie turned a passion into a business when she launched her first jewelry line, House of Harlow 1960, in the fall of 2008. The collection takes its name from her young daughter and features design influences from 1920s, ‘40s, and ‘60s fashions, as well as Native American and tribal decorative traditions.
