Amanda Seyfried looked radiant at the Hollywood Dear John premiere in a duo toned halter dress with a plunging neckline that displayed her fine assets by Giorgio Armani. If you look very closely, there is a see-through panel that keeps the V-dip together so that double-stick tape is not needed. Ingenious design!

Was Amanda's dress a hit or a miss?
