Excerpt from her interview on VogueGirl:

Q. Which is better? G-Dragon’s style or T.O.P’s?
Hara: G-Dragon’s style. He is the most awesome celebrity who wears stylish clothes even in daily life. I’m sure he’ll look good even w/o stylists.

IMO, whoever she chose I have nothing to say. GD&TOP are both stylish ^^
