Miss Universe was first founded back in 1952 as a marketing stunt by a California-based company which, through the years, became one of the most-watched pageants in the world. So far, there have been 68 Miss Universe winners. Out of those, the Miss Universe of 1997 (point 6 in this article) was the oldest among them, and the winner of 2001 (point 7 in our article here) managed to get a role in Aquaman.
By comparing the winners of Miss Universe, we can see that through the years the beauty standards have changed both for body types and looks.
