Why are Somali girls so pretty?

They are probably the hottest black girls I HAVE EVER SEEN! People say it's cause they are a mixed race but many say they are the original african people from the horn of Africa. They have smooth skin, big eyes, high cheekbones, cute button noses, and nicely shaped lips. Also they have really soft hair, it's like biracial hair but even softer. How come other (full) black people don't look like that??
