Summer may still be in full swing right now, but with just a few more weeks until you're back in the classroom, it's time to start thinking about trading in your bikinis and boardshorts for backpacks and books.

This year, we got a head start on back-to-school shopping for girls and guys, and scouted out some of the season's best trends.

Every pick is under $50, leaving room in your back-to-school budget for those other fall essentials you've been eyeing. Click through the slideshow below for our top 15 styles for Fall 2012.
