Junk Food Clothing Co. is trying an off-the-wall concept to sell its vintage-inspired T-shirts, literally.

The Culver City apparel company launched two digital “stores” on the hallway walls at the Westfield Topanga mall last month and plans to roll out more in other Westfield locations in the next year.

Andrei Najjar, vice president of marketing and brand development for Junk Food, said the company is trying to stand out in an increasingly competitive online retail market.

“Our offices are more of a creative lab than anything else,” he said. “We’re lucky in that we’re kind of small, we’re lean and we have the freedom to just imagine.”

The stores are wall-mounted, window-size light boxes that display images of limited-edition T-shirts. Each image has a corresponding quick-response code that a shopper can scan with a smartphone to purchase online and have it shipped home.

The digital stores, which were tested earlier this summer at the San Diego Comic-Con, are not the first unusual thing the clothing company has tried. Also this summer, Junk Food partnered with Boston-based clothing company Johnny Cupcakes to drive a “food truck” through Los Angeles, as well as New York and San Francisco, to sell its garments. In August, the company gave T-shirts to everyone on the inaugural flight of Virgin America’s route between San Francisco and Washington, D.C., to promote Rock the Vote, an L.A. non-profit.

The company, which was founded in 1998, sells its T-shirts wholesale to more than 4,500 stores worldwide. The goal of the digital stores is to bring more customers to the company’s website, Najjar said.

“We still have to pay a lease to the mall, but it’s essentially like a marketing expense,” he said. “There’s no need to staff it, so it’s really very low maintenance.”

Mark Douglas, president and chief executive of Culver City online retail marketing firm Steelhouse Inc., said the digital stores are part of a larger move in retailing to marry the online and physical worlds.

“There is a lot of movement now of, ‘How do I bring everything we have going on online for our brand? How do I bring that to the in-store experience?’ The difference in this case is that there isn’t the immediacy of being able to leave the store with the product.”
