What the Chung blogger Jamie Chung has become something of a fashion socialite since her days on "Real World San Francisco." (Visit her blog and you'll be absorbed for hours.) I'm obsessed with her red Aimee Kestenberg Backpack, particularly when paired with an all black-and-white ensemble like this one.

If the thought of wearing a backpack again gives you cold sweats and memories of AP calculus class and god-awful braces, you're not alone. I thought the same thing until I came across this street style photo from London Fashion Week. Her backpack is completely sophisticated, made of beautiful leather and can easily be worn to the office. A high quality look like this will never go out of style.

You could play it safe with your backpack selection by going with a basic black or brown you can wear with anything. But these are backpacks. You'll already want to wear them with everything because they fit all your essentials and they don't give you Poshitis. A bright color and structured shape, like this one on Koko Luxe blogger Rachael Jane, will garner endless compliments.

You can definitely splurge on a designer bag if it carries two purposes right? This bag from BCBG Max Azria's spring/summer 2014 collection is one part bucket bag, one part backpack, so you can carry it whichever way suits you.

Cara Delevingne is the type of girl who can pull off a backpack. It's the cool-girl accessory that, when worn with a leather jacket and a beanie (like Delevingne often does), makes you feel like an off-duty model. This model even has her own bag line with Mulberry. (That adorable mini satchel/backpack she's wearing is part of it.)
