Backpacks are so handy but it can be really hard to find one that doesn't look too "schoolish." This Metallic Nylon Backpack by Just Cavalli fits the bill for me, though, with its casual floppy nature combined with a healthy dose of trendy metallic style and "flash" appeal. Strikes me as a great bag for the girl who likes to wear stiletto heels with her blue jeans. Made of woven nylon with snakeskin- printed leather trim, it has pockets galore (obviously, it is a backpack after all), a snakeskin-printed textile lining, and a magnetic closure at the top. $750
