Heading back to school or just want to check out some rad fall wares? Then head to Berkeley's fave eco-friendly boutique Convert, which will be hosting a "back to cool" trunk show featuring equally green label Prairie Underground. A local stylist will be on hand to help guests cobble together stylish ensembles, while the winner of Convert's school-themed Facebook contest (just post a picture of yourself back in your school days here!) will be announced and walk home with a snazzy Prairie Underground jacket. Of course, there will be snacks galore, including PB&J cupcakes and nostalgia-inducing Capri Suns. Learn how to make the grade in style below.
