Camille Charriere from Camille Over the Rainbow blog, before Acne, Paris, September 2013.
Love this look on Camille: the pinstripe sweater (I think it is from Mango) works brilliantly with her cropped pants. Another way to wear the pinstripe sweater here.
Recreate Camille's look (kind of):
Pinstripe sweater: Stella McCartney pinstripe sweater
Cropped pants:  J.Crew Eaton cropped pants, ASOS crop pants in linen, The Row Eli cropped pants, or Thakoon seamed cropped pants
