Puerto Rican model Joan Smalls, after Stella McCartney, Paris, September 2013.
The harness over Joan's leopard print blouse sort of looks like it has been inspired by girls wearing backpacks over their shoulders...
Recreate Joan's look (kind of):
Equipment Signature blouse, Maje Dindi leopard-print shirt, Tamara Mellon leopard-print blouse, Equipment Slim Signature blouse, Nasty Gal Hell Cat blouse, or Sonia by Sonia Rykiel Wild Dots blouse
