It's no problem to say since 100 years ago chicks have gotten hotter and hotter. So if this continues how hot will chicks 50 years from now look.
Exhibit a half flip/white cyborg
Most of the genetics for "hotness were already here, it's just that 100 yrs ago, women didn't really take care of themselves, and the men looked for "wifey" type chicks.
I saw a pic of a Quadroon from the 1800's, and that chick was banging like nobody's business. Also, Josephine Baker was hot as well.
What you will see though, is that in 100 yrs, many of the women look similar to Brazilian, Dominican, or Colombian women, as there will be a large population of mixed people of color...
And then America will finally start winning the Miss Universe...
