Celebs always look chic and stylish when they hit the red carpet, but only a true fashionista can transition her style from Hollywood glam to everyday chic. From lunching in New York to shopping in LA, the stars sizzled as they strutted their stuff on the street this week.

Kate Middleton looked as lovely as ever at during her tour of Winmalee Guide Hall in Australia on Thursday, wearing a blue and white Diane Von Furstenberg wrap dress, navy platform wedges, a matching navy clutch and silver jewelry. To complete her look, the brunette beauty kept her tresses down in a sleek, center-parted straightened style and opted for a more natural look with minimal makeup.

Reese Witherspoon looked radiant and relaxed as she shopped in LA on Wednesday wearing a crisp, white blouse under a Current/Elliot denim jacket, paired with black jeans and a white, wide-brimmed fedora. The mother-of-three dressed up her ensemble with floral-print pumps, a turquoise handbag and a coordinating necklace. To complete her look, the 38-year-old actress wore her hair in a low ponytail and concealed her face with black, cat eye sunnies.

To finish off her look, the blonde bombshell wore her hair down with loose curls and hid her face with large-framed sunnies.
