I saw/met Chiara last night and let me say that she is SOOO EFFING pretty. She does look ALOT like Amanda Moore but with a younger and softer look.
Regarding the Chiara vs. Bianca debate. I think both are very pretty but they have different types of looks. Bianca's look is more sultry and mature. I think that's why Bianca is more successful at this point. It also helped that when Bianca had her hot season (Fall '05) she was a different look in comparison to girls of the moment (i.e. Daria, Gemma). Although Chiara is very pretty there isn't anything really different about her and she doesn't yet have that allure that the successful models have. This is all just my personal opinion, of course.
PS As the italiana, eword, mentioned Chiara is pronounced as "Kiara". Anche, ho studiato l'italiano per un anno.
