Cailey Fiesel, 24, has submitted photos to Manhattan Supreme Court showing the suspicious bulge in the hem of her brand new Zara dress - and “at least one of appendages protruding”.

Ms Fiesel, from New York, only realised the rodent was there when she was already wearing the dress at work.

She is suing for unspecified damages not only for the emotional distress, but also for a large rash from a “rodent-borne disease”.

A spokeperson for Zara told TMZ: “Zara USA is aware of the suit, and we are investigating the matter further. Zara USA has stringent health and safety standards, and we are committed to ensuring that all of our products meet these rigorous requirements.”
