Im not wrong as I study anthropology and I know what Im saying. If you still have doubts... well:
1. Natalia is a Slavic perhaps, but with very strong Baltid admixture from her father`s side.
2. Carmen Kass is Estonian and Estonians along with Finns are Finno-Ugric (this type is from Ural region of Russia) people, which is not even Indo-European.
3. Karolina is a typical alpine slavic girl.
4. Eugenia ia a Tatar (i.e. of Turkic-Asian origin).
5. Hana - same as Karolina.
6. Marija Vujovic (as I just wrote you in my answer to your message) is Serbian and Serbians are only adopt Slavic culture and not belongs to Slavs geneticaly (they re obviously Meditteraneans).
7. Natasha Poly has Finno-Ugric origins.
8. Valentina is a very typical and simple-faced Slavic girl.
9. Inguna is Baltid as you noticed.
Still I think that if they just wanted to write about models from E.Europe they couldnt use the term Slavs as it sounds very wrong.

Also I think that those guys forgot about such SLAVIC girls as Polina Kouklina or Anja Rubik
