Backpacks are back in vogue, and Topshop's trend-led styles are a great way to update your closet. The casual cotton drawstring bags hark back to the 90s with vibrant prints and rainbow shades. Rather more elegant are the structured leather styles in shades of putty and biscuit, proposing a directional alternative to the classic tote. Infinitely cooler than your battered old schoolbag, Topshop's backpacks are a new season essential.
