Dutch model Mirte Maas, after Armani Prive, Paris, July 2013. 
Love a well-cut shirtdress: easy to throw on with sandals for warm days, and ankle boots like Mirte is wearing for when the weather turns cooler. 
Recreate Mirte's look (kind of):
Camilla and Marc Quarterdeck shirtdress, T by Alexander Wang shirtdress with collar pin, DKNY oversized shirtdress, Topshop contrast panel shirt dress, Helmut Lang Helmut Ghost shirtdress, McQ Alexander McQueen hook and eye shirtdress, ASOS shirtdress with strap detail or Glamorous swing shirt dress
Tory Burch Milan mid heel suede booties, Luxury Rebel Shoes Pandora zip booties, or Topshop Amelle ankle strap boots
