Such stunts have led to a public battle of wits between Kidult and designer Marc Jacobs, who used images of Kidult's spray paint attacks and printed them on hats and T-shirts and sold them.
Kidult could not be reached for comment.
It's a question worth exploring: Does commercialization detract from an artist's authenticity?
Jeffrey Deitch, former director of the Museum of Contemporary Art in Los Angeles, would argue no. "Art evolves," he said.
In 2011, the museum showed a well-known exhibit named "Art in the Streets" that looked at the global development of graffiti into street art throughout history. "This is one of America's big cultural exports. You go all around the world and see echoes of 'Wild Style,'" said Deitch, who was the lead curator of the exhibit.
He believes that artists represent the voice of a generation, and by including street artists in museums, galleries and clothing, artists are given a platform to show their talent and innovation.
The popularity of these collaborations might present an annoyance to those who view street art as pure vandalism. While Deitch says he understands the anger of a shop owner who has to remove graffiti from a storefront in order to maintain business, he notes that street art is bigger than that -- it's often an expression of social and economic unrest.
"A lot of the important art forms are started by renegades,' he said, noting jazz music in speakeasies and rock music that "made the neighbors angry."
"This is where culture starts."
Street art-inspired styles will likely make their way into your local retailers within as early as the holiday season, said Julian, the trend forecaster.
Deitch championed the lines' promise of accessibility: "Not everyone can afford a $10,000 painting, but almost everyone can afford a $15 shirt."
