I just had to post these kenzo bags from the mens catwalks recently. Backpacks have made a huge come back and especially in the dressy area, they are being worn with suits and all kinds of fashion formal outfits.
Check out this slouchy rucksack style with snake skin detailing.
And this ultra flat, odd proportioned backpack which sort of reminds me of an artists back. You expect to see a canvas, sketchbook and some paints fall out to be laid out for some plein air painting in a meadow somewhere... or maybe thats just me dreaming of being on holiday.
