Yeah, I can understand that .
To me Irina and Adriana look more alike than Catalina to either of them.
But I think they all have their own special something though .
I think the notoriety of Adriana has caused almost every olive skin, bright eyed model that comes along to fall into the "Adriana look-alike" box
(like Nataliele and Thais O look nothing like her to me). But South America (and other parts of the world) just has a lot of peope with olive skin and bright eyes . She was just one of the first to become big when more Brazilians were being accepted .
