I’m crazy in love with monolid eyes. They’re beautiful. Here’s an overlay giving your Sims realistic monolid eyes. And not only for your Asian Sims, did you know that:
The monolid eye, also called epicanthic fold, is not only prevalent in Asian populations. It’s also a prevalent genetic trait in Polynesia and Micronesia, as well among the Native American, Inuit, Yupik or Aleut people. Even in Europe (Icelandics for example, look at the stunning eyes of the singer Bjork!) or Africa, like the Khoisans, known for their unique culture and incredibly beautiful eyes.
