Those are standard modeling agency headshots. They are taken without any make-up on so whoever sees them (the photographer, make-up artist, etc.) knows what they have to work with. Models are picked based on the overall structure of their face (if shooting faces up-close), the rest is make-up, lighting and retouching. High fashion is about exaggeration; uniqueness through mild weirdness. It's about picking models based on their potential for standing out, a living canvas.
I know and have worked with a few models that you'd probably never notice on the street, at best you'll consider them "pretty", but not "hot", yet they produce some strikingly beautiful images. Not to mention that models have to keep their weight down so they all look like sticks in real life.
