Beautiful (both inside and out), Doina Ciobanu, before Chanel, Paris, March 2012.
I love this look on Doina. She is still a teenager but wears this sophisticated, grown-up look beautifully. In fact I think clean, crisp masculine tailoring like this would work on women of almost any age... and it is entirely suitable to wear in a more conservative workplace.
Recreate Doina's look (kind of):
Stella McCartney grey tailored blazer and grey slim fit flared trousers  or Reiss royal blue jacket and tapered slim trousers
Theory Larissa classic white shirt
Christian Louboutin Décolleté 100 glossed-leather pumps or ASOS shine patent pumps
