For the fall/holiday 2011 campaign, OP embraced the great out doors and brought back familiar faces Mark Salling, Chord Overstreet, Rob Kardashian, Aly Michalka, Kat Graham, and Brenda Song. The crew hikes, canoes, roasts marshmallows and even climbs into sleeping bags while showing off the holiday collection. OP is available exclusively at Walmart, and while you may not be able to scoop up their get-ups just yet, you can still check out the campaign shots & go behind the scenes.
