Models, nor their mothers, do not get a say in how they are dressed for shows, magazines, etc.
There have been several see through/sheer/naked looks on the runways for years.
Obviously this dress was designed and if she hadn't worn it someone else would have.
I am not a fan of the Ks but this is one of those instances where the criticism just shows that people are more critical of them than others...
Do they deserve it? Perhaps, but I do find it curious that people are so invested in criticizing them/ their dislike for them that they stretch situations like this.
