This is the original Allen Jones chair on which Dasha Zhukova sat for the photoshoot. The copy on which she sat shows a black mannequin but that is what I would call artistic liberty,
But to call it racist just because the colour of the back rest, seat and parts of the bottom is black, I think is absurd. It will be equivalent to calling me racist for wearing a pair of black shoes instead of say brown. Or, perversely, sitting on exactlty the same chair with white as the predominant colour with the mannequin being white.
Being politically correct is getting to be absurd.
