If we're talking the hottest and most unique with beauty it's going to be Africa, Brazil, US/CAN, and I hate to say it, but I'm hopping on the Russian Train.
First off, representing the motherland, you have Liya K., Iman, Yasmine W., and Alek four very distinctive beauties, but all incredibly fierce. The fact that Iman is fifty something but looks like she is 30 (without makeup), speaks so many volumes. Black does not crack (especially coming straight from the source). If any other chicks are looking like Iman in their fifties, then I will bow down to the other countries.
Second is Brazil. Talk about a melting pot and a place where white women actually will lie and say they have some African so they can be considered beautiful. You can't go wrong with that kind of thinking. LOL. First there is the almighty Gisele who can do no wrong IMO. Then you've got Adriana, Alessandra, Ana Hickman, CINTIA DICKER, Aline Rezende, and Milagros Schmoll. It's called, that's hot.
Big up to the US/CAN for keeping it real too. You've got Tyra, Claudia, Christy T., Linda, Kathy Ireland, Pat Cleaveland, Naomi Simms, Beverly Johnson, Karen Alexander, and Gia. It really doesn't get better than that.
And now I'm choosing Russian/Slavs over my other favs UK (only because of Naomi Campbell-after Iman-is one of the the most beautiful models I've ever seen) and the Scandinavians. Why? Three models. Katjia S., Natasha Poly (a freaking professional-check out her mishap on the VS 05 runway), and Anja Rubik. Those girls are freaking gorgeous and other wordlywithout looking weird like Jessica Stam, Gemma Ward (ew!) and Heather Marks. And of course there is Natalia V. who might just be one of the most perfect creatures in the world. I think Euginia V. is fugs, but the girl can walk and she's got presence. There is something regal about her. So go Russia go.
