26 photos that show how models have changed over the years

Just as fashion has undergone drastic changes throughout the years, the models who help bring the designs to life have evolved as well.

In the past, models were often a major factor in establishing society's standards of beauty. Now, as beauty standards become more inclusive, they're shaping the types of models we see making their way down the runway.

Here are 26 photos that show how models have evolved throughout the years.

Illustrator Charles Dana Gibson painted beautiful women in his "Gibson Girls" paintings from the 1900s.

Illustrator Charles Dana Gibson created the image of the "Gibson Girl" by observing various women in his daily life. One of the most famous models for the paintings was Camille Clifford, whose hourglass figure came to shape the ideal look for many American women.

The 1920s saw the rise of the Flapper, an image built on a more rebellious and free-spirited nature.

Flapper-style dresses — which often featured pleated skirts or fringe and feather detailing — and a sense of attitude came to dominate much of the imagery in the fashion industry.

Before traditional supermodels become popular, Hollywood stars were huge fashion icons from the 1930s through to the 1950s. Marilyn Monroe was especially influential in the '50s.

Monroe became a movie star in the 1950s after a series of small modeling gigs led to her big break.
