Here's one wild reason to trade in your usual PB&J with the crusts cut off for, oh, a tin of beluga and some blinis this fall...

Jil Sander's fall 2012 menswear collection, hitting stores right now, featured one extraordinary accessory--an absurdly luxurious version of that grade school staple, the brown paper lunch bag. As W reports, the label has "taken the humble lunch bag and rendered it in leather, rolling out the edges and giving it a chic, folded-down makeover with a magnetic clasp." Does that make it worth...wait for it...$630!?

For those with, ahem, humbler tastes, there's also a $290 paper version. (Actually, it's coated paper, with metallic vents and a very prominent Jil Sander logo, naturally).

They're meant to be carried like clutches and stow more than just baggies of carrot sticks, but still. Are you as WTF over this as we are!? Discuss!
