"Gatsby 1920s long hair" refers to the iconic hairstyle popularized by the character Jay Gatsby in F. Scott Fitzgerald's novel, "The Great Gatsby." This hairstyle, characterized by slicked-back longer locks, became emblematic of the Roaring Twenties, an era known for its opulence and excess.
Gatsby's long hair was not only stylish but also conveyed a sense of freedom and rebellion against societal norms. It was a symbol of the era's newfound individuality and a departure from the shorter, more conservative hairstyles of the Victorian era.
