Spanning the 1920s to the mid 1930s, the Harlem Renaissance was an intellectual, social, and artistic explosion that produced a new black cultural identity. It was known as the Negro Movement. Many black writers, poets, photographers, and specifically musicians came from the South directly to Harlem, New York; a place where they could freely express themselves. It incorporated Jazz and Blues and attracted whites to speakeasies to listen and dance to what blacks were producing. Harlem became the Mecca of Jazz and Blues music.
The Fashion Institute of Technology in New York City has an African American student population of less than seven percent. Even worse, designers of color represent less than one percent of designers available in major department stores. It isn't that black people just aren't designing. The answer might not be as simple as most people think.
