Another girl whose style I am obsessing over is Aussie beauty Margaret Zhang, Editor of Shine by Three blog and commerce/law student.
I adore the simple white column dress (white dresses like this remind me a little of Carolyn Bessette Kennedy's  Narciso Rodriguez wedding dress) teamed with the blazer and beaded scarf necklace. Simple, elegant and beautiful.
Recreate Margaret's Look (kind of):
BCBGMAXAZRIA white T-back dress (love three four things about this dress: it skims rather than hugs the body, it isn't too "bridal" nor beachy, it isn't just for after-dark, and it has an interesting back — perfect for showing off sun-kissed skin).
Roarke coralline scarf necklace  (from Anthropologie US). I also love the peter pan collar necklaces from Dannijo this season — an easy way to update a simple outfit, and achieve a similar look to the scarf necklace. Dannijo Hixson collar necklace or Dannijo bronze chain link peter pan collar both investment pieces which would last for years.
And then just add a punchy coloured blazer of your choice (with sleeves rolled up of course!). Try Elizabeth and James Spring Jim blazer in tiger lily or Rag & Bone 42nd Street blazer in turquoise.
