Kate Mara delivers a hardcore, braless tease on the red carpet at the Bucking Fastard screening during the Venice Film Festival. The stunning actress steps out wearing a dangerously low-cut, backless gown that leaves her almost completely exposed. The plunging front features a deep, sheer window that directly flaunts her bare cleavage and spilling tits for the flashing cameras. Held together by nothing but thin string straps across her fully naked back, the revealing top flashes major sideboob, while the skintight black sequined skirt ruthlessly hugs her slender curves. The entire look turns a prestigious premiere into a pure, shameless exhibitionist showcase of her naked flesh.
