I love both these red carpet looks on Rachel McAdams and Kirsten Dunst and their use of the black satin ribbon-headband. Rachel's top knot is perfect. I love the use of the headband with an updo, her red hair and the pale pink lip, done! Kirsten looks very Brigitte Bardot inspired and let's be honest, you can never go wrong with that.

For continued black satin headband-spiration look no further than Gwen.
