These women do not exist. They each are a composite of about 30 faces that I created to find out the current standard of good looks on the Internet.
On the popular Hot or Not web site, people rate others’ attractiveness on a scale of 1 to 10. An average score based on hundreds or even thousands of individual ratings takes only a few days to emerge.
I collected some photos from the site, sorted them by rank and used SquirlzMorph to create multi-morph composites from them. Unlike projects like Face of Tomorrow or Beauty Check where the subjects are posed for the purpose, the portraits are blurry because the source images are low resolution with differences in posture, hair styles, glasses, etc, so that I could use only 36 control points for the morphs.
What did I conclude about good looks from these virtual faces? First, morphs tend to be prettier than their sources because face asymmetries and skin blemishes average out. However, the low score images show that fat is not attractive. The high scores tend to have narrow faces. I will leave it to you to find more differences and to do a similar project for men.

My other two images on attractiveness are here and here.
