By Thursday, Twitter had latched on to the story, and to Urban Outfitters, with a vigor not often seen on the social networking site.

Users rebuked the clothing store for ripping off an independent artist once again so that they could mass produce the item and sell it back to customers at high prices. In the photo above, the similarities between Urban Outfitter’s I Heart Destination necklace line and independent artist Stevie Koerner of tru.che’s United/World of Love line can be seen.

Urban Outfitters soon sent back a tweet that said they were looking into the matter (see below), and blogger Amber Karnes, who first spread the story on Twitter, wrote that Urban Outfitters was going to pull the necklaces from all stores immediately. The link to the I Heart Destination line on Urban Outfitters’ Web site went dead.

A request for comment from Urban Outfitters was not immediately responded to.

Koerner of tru.che had originally written on her Tumblr:

“One of my lovely customers sent me a message today...My heart sank a little bit.  The World/United States of Love line that I created is one of the reasons that I was able to quit my full-time job... I understand that they are a business, but it’s not cool to completely rip off an independent designer’s work.”

But by Friday, she had little to worry about. Amber Karnes’ tweet, which had a link to Koerner’s Tumblr post, was retweeted hundreds of times. The phrase ‘Urban Outfitters’ soon became a trending topic in the U.S, Canada, and the United Kingdom. Twitter users barraged the Urban Outfitters Facebook page with criticism. And Twitter users started to call the situation a “PR Nightmare” and a “smackdown.”
