No, I agree. Kumi wasn't trashy in Cherry Girl. The only time she was very exposed was in the denim skirt outfit (which was really revealing and all, but she looked clean-****ty, if anything, not dirty XP), and the whole video wasn't about sex like some of the others.
EDIT:
HOLY CRAP. I just re-watched Cherry Girl right now, and my gawd.... The scene where she's acting as a bartender... HOLY FREAKIN' PADDED BRA!!!

Her boobs in that scene look so freakin' huge compared to the others, lol.
