I don't find it attractive because I am attractive to women. Women don't have to expose their butt cheeks to get attention. If a woman like to do it then they should not complain about them finding a jerk because those are the kind of guys who will approach them. Some things can be prevented by simply dressing appropriate in public. I wouldn't want my daughter to dress that way so I wouldn't want another woman to dress that way either.
It depends on if the girl suits the shorts what I think. If she suits the shorts then yes it can very attractive. I once was waiting in line at Subway and this girl in front of me had those shorts on showing her butt cheeks.
