As you’re cleaning out your closet and sifting through a semester’s worth of trendy H&M purchases, remember not to toss everything into the trash. Fashion in 2011 definitely had its lows (hipster headbands and playsuits, anyone?), but as any frugal fashionista knows, every season has pieces you can incorporate into the next season’s wardrobe.
