It's a company called Bad Kids Clothing, which describes itself as "an EDM-inspired clothing line with a strong foundation in selling neon apparel." The shirt in question (dubbed the "The Doherty&") lists the names of Swift's (known) dating partners.

As soon as word got out about the shirt, it didn't take long for Swifties (Taylor's rabid fan base) to jump to attention and take action.

In a recent blog post, Andi Cross of Bad Kids gave her POV on the controversy. "The shirt originally started out as just a light hearted joke between friends," all of whom "enjoy the pop tunes of T-Swift." Cross writes that she "was joking with friends saying I wish I had as many hot boyfriends as Taylor – so hard to even get a solid date around here! You go T-Swift, you're a babe! A simple, fun, harmless joke however, turned into an online sensation over the weekend and frankly shocked the Bad Kid community to the core."
