Definitely one stylish lady you need to know, Alexa Chung, this cool-brit-chic, french pop inspired and it girl is another style inspiration for me. She's the presenter of british show, "Popworld" , before that she used to model.
You can see some Françoise Hardy, Jane Birkin, Marianne Faithfull in her looks and she also cites being inspired in movies such as Doctor Zhivago, Annie Hall, Blowup, Picnic at Hanging Rock and Masculin, Féminin.
To get a hint of her style I recommend:
-Neutral palette in your wardrobe: lots of whites, black, navy blue, gray, denim
-Plaid prints and striped shirts
-Blazers (black, blue), a black leather jacket, knitted sweaters and cardis
-Simple short dresses, high waisted skirts, jumpers, skinny tight pants in dark colors.
-Flats,loafers and vintage heels (mostly black).
-Big vintage leather bags and totes
-60's kitten-like black eyeliner, lip balm and a touch of blush
-Long, plain chain necklaces and sometimes with a charm on it.
