Instead of apologizing and explaining why it allegedly ripped off a necklace from an independent jewelry designer, Urban Outfitter is fighting back.

The retailer is saying that the designer Stevie Koerner, who sells her jewelry on Etsy, is making baseless accusations.

In a blog post from May 28, the retailer said:

“A quick search on Etsy for ‘state necklace’ reveals several other sellers with similar products (as seen here on Regretsy) who offered their wares as much as a year earlier than Ms. Koerner.

“We are not implying that Koerner stole her necklace idea from one of these other designers, we are simply stating the obvious—that the idea is not unique to Koerner and she can in no way claim to be its originator.”

So, basically, creative lightning may have struck twice—in different places about the same time.

The uproar began last week, when Koerner posted two images to her Tumblr page, one showing Urban Outfitter’s necklace design and another showing her own. She said the retailer ripped off her design.

The Tumblr post sparked a boycott of the chain, fueled by tweets and several Facebook groups. In a surprising move, celebrity Miley Cyrus joined the fray when she tweeted: “Love that everybody is hating on Urban Outfitters.”

She followed that statement with this tweet: “Not only do they steal from artists but every time you give them money you help finance a campaign against gay equality. #SHADYASHELL”

Cyrus is referring to Urban Outfitters founder Richard Hayne’s contribution to Rick Santorum’s political action committee. Santorum, a former Republican senator, has made controversial statements about homosexuality.

In its blog post, Urban Outfitters also said that it wouldn’t normally respond to allegations such as those made by Koerner, but “the media response to her campaign is threatening to impact the dozens of independent designers we work with on a daily basis.”
