Margaret Zhang from Shine by Three blog, after Theyskens' Theory, NYC, September 2012.
Absolutely adore the way Margaret has styled her hair here... paired with her delicate drop earrings and white dress it is such a pretty, soft look. And balanced with the street cool Isabel Marant wedge sneakers! 
Recreate Margaret's look (kind of):
White dress: Thakoon Addition ruched front shirtdress, Rag & Bone Adele dress, McQ Alexander McQueen shirtdress, Topshop Clean utility shirt, DVF Montana dress, or Ellery shirt dress
Drop earrings: Juicy Couture pave feather drop earrings, ASOS Pretty drop earrings, Lulu Frost pave earrings, or Topshop Premium earrings
Isabel Marant Bekett wedge sneakers,  Ash Bowie wedge sneakers, or Ash Cool wedge sneakers
Another way to style a white summer dress (via the lovely Tamu).
