In the language of colors, red is a symbol of femininity, even of sensuality. No wonder then that the Hollywood stars make their favorite color! But still we must assume ...
As Katherine Heigl who almost ended up half-naked when his sling slipped, as Eva Longoria whose Ralph & Russo draped dress hides a dizzying cleavage ... in the back or like Teri Hatcher in his bright red dress that highlights his generous cleavage and distracts the eyes of these gentlemen of his last facelift (missed).
While blondes favor the white dress (starting with Diane Kruger, Taylor Swift or Virginie Efira), Hollywood brunettes have a clear preference for red. Two schools, two styles. CQFD!
