Madonna strode the red carpet in a beautiful dress by Vionnet at the Venice Film Festival, where she is debuting her film W.E. Her dress choice has extra special meaning: costumes for her film were reproduced from the original Madeleine Vionnet archive. Madonna looks ultra elegant, even with the bright red sunglasses. Her blue silk satin dress is beaded with red butterflies, making for a dreamy effect. For all the angles on Madonna's glamorous outing, click the slideshow.
