.Sorry all , i Love Yoon so much . Don't know why look at this album , i can't be happy at all
I can understand where you are coming from. Though, as a male I will admit I do enjoy/admire the partially clothed picture of YEH on the couch. As one of the older members of this site I do understand a lot of the negative conations associated with the image (both exploitative and moral). The photo posted by Vegaspink is a lot more universally acceptable, and the second picture if it were zoomed in to showing from the shoulders up would also be more tasteful.
However, YEH is alas limited by the needs/wants of the industry. In addition, the recent trend of magazines (W Magazine and Dazed n Confused) might of been chosen by her intentionally (idle speculation on my part) to change her image slightly.
As an American I am unsure if this situation is common in the Korean entertainment industry. However, YEH overall tends to be cast in roles that are sympathetic/endearing or even girl next door type. (NOTE: I have not seen Black mini-dress, so I cannot comment if that breaks the type cast or not). The two above mentioned Magazine are going for a more mature sexy image. However, as I said this really is idle speculation and might be nothing more than coincidence.
