Black and White for Winter Style

Black and white... the most common of our basic colors. These stars know exactly how to combine the style for awesome looks.
  Blazer, leather, and pumps topped with sheer fab.  Totally loving Jessica's sleek pony, giving her look classy sophistication.  Kate Upton's Scarf Swag top adds femininity to her leather pencil skirt.  A flirty and youthful look with a steep neck line and flouncy skirt looks great on Lily Collins.
