If you haven't considered a backpack for your everyday stuff holder, now's the time. There's cute backpacks-a-plenty out there, and they don't have that icky wiff of old sandwiches and mouldy mandarins like our school bag did.
In leather, floral fabrics or minimal tech fabrics, these backpacks sit midway between schoolkid nylon numbers and super slick Prada-esque knapsacks worn by city ladies in business suits and white runners.
If you're closer to school-aged years, then a backpack proves comfortable and familiar. And if you're getting on a bit, like, over 25, they have that warm feeling of nostalgia.
As usual, eBay is an excellent source for backpacks. There's a few vintage leather ones kicking around there at the moment. A huge canvas number and a patchwork vintage bag in particular has caught my eye.
Unlike your school bag, don't go kicking your new grown-up backpack around the floor of the bus. Especially if you go for the deluxe Ann Demeulemeester version.
