This isn't pre-fall, but Summer 2012 of the Swedish edition and issue #61.
But they are wearing pre fall and the whole ed is with balenciaga pre fall and other brands. The previous issue with Caterina Ravaglia was credited as spring/summer 2012.
^ I was confused too, so I asked them on Twitter and they replied that this issue is Bon #61 Summer 2012. It's the Swedish edition which comes out four times a year whereas the previous issue with Caterina Ravaglia etc. was "Spring/Summer 2012" and the international edition.
