Ah, the always highly subjective "prettiest girl" question. As we all know, beauty is in the eyes of the beholder but as far as NYC Asian girls, this is my list.
1. Koreanna
2. Chanel
3. Arie
4. Momo
5. Tori
6. Hannah
The K-girls win every time in my book... but a shout out to pretty C-girls: Shirley, Yoyo/Candy, and Sara... but somehow their beauty had less impact on me, as apposed to the above mentioned. And I'll mention former Pink31 Mia (K-girl) as well... very pretty, but it didn't affect me very strongly for whatever reason.
