Historically, fashion has been predominantly focused on promoting a narrow beauty ideal associated with slimness. The perception of beauty has changed over time and is influenced by societal, cultural, and historical developments. In the early 20th century, curvaceous figures were celebrated, exemplified by icons like Marilyn Monroe. However, as fashion evolved, the ideal shifted towards a more slender body shape, perpetuated by the rise of high fashion and the changing ideals of beauty.
