Here is a partial collection of my sims made as young adults from CAS.
The women: On the top left, my simself's wife back from 2009. Also on the top, 3 women from my fruit named family in Twinbrook. Bottom left and middle are girls from Bridgeport and bottom right is my witch from Moonlight Falls.

Do they look too similar? Do they look like they have been made by the same person? I don't see much of a pattern. Of course beauty is out of question here, I don't want all my sims to be supermodels.
