Scarlett Johansson wore a Proenza Schouler Spring 2012 dress for an appearance on 'The Late Show with David Letterman'.
The strapless cocktail dress with a geometric print bodice & teal coloured skirt highlighted those famous Johansson curves perfectly.
However, I would have kept the bodice long, it's more flattering like that.
An updo, red lips and white heels were the finishing touches.
