Koda Kumi's image was always sexy, I don't see why it's a problem and she doesn't always wear revealing clothing. Sometimes I think since she has a curvy body, clothes look "sexier" on her than they would on someone who doesn't have her figure. She looks great and is a welcome contrast in an industry that too often relies on manufactured innocence to promote artists.

I'm not fond of Mika's hair at the moment (looks like a weird, spiky mullet) but I'm siding with those who think that the artists don't need to change their image. Whatever each of them is doing, it's working.
