From my experience girls fall for good looking guys despite their ethniticites. In writing so , Croats, Serbs, Montenegrins have an ideal phenotype among girls of eastern Slavia.
I also know Russian and Ukrainian girls like the Belarusian guys. We are healthier drinking less than Russians and Ukrainians. There are girls in Russia, Ukraine, Lithuania, Latgale who like blond or light brown haired and blue or gray eyed guys too.
Belarusians are known for blondism and light eyes among eastern Slavs. The nickname of Belarus is a blue-eyed country.
We also have many people with dark hair. But dark eyes will be unsual in our community. We have a common saying “Dark eyes cannot be trusted” .
