Abercrombie & Fitch, the basics retailer that is the cornerstone of most malls, learned a valuable lesson: Do NOT mess with Swifties. 

Taylor Swift fans, known for their disciple-like devotion to the singer, launched a campaign to have a shirt with the slogan, "#More Boyfriends Than T.S." removed from A&F stores and succeeded! The offending tees will no longer be sold.

The fans got vocal and started a Change.org petition and they contacted A&F's PR department to express their anger at a shirt poking fun at their heroine's love life.

A&F leapt into damage control mode and decided to yank the tees from their stores. The Swift army won the battle and the war.

Apparently, an outgoing message on the company's PR department voicemail said the following: "Thank you for calling Abercrombie & Fitch public relations. If you are calling regarding the Taylor Swift t-shirt, please note this is no longer available."

The company's backpedalling tweet is below.

Watch, they'll try and say the "T.S." refers to someone else. As for people who actually bought the shirt before it was pulled? Well, consider yourselves owners of a pop culture collector's item. Wonder how much they'll go for on eBay...

We also wonder if T. Swizzle's famous ex, One Direction's Harry Styles, had a chuckle at this fashion gaffe. Maybe he'll be their next spokesmodel. Nah, he has too many tattoos and the powers-that-be at A&F only like pretty bodies. Remember, the brand came under fire earlier this year when CEO Mike Jeffries said that the company only makes clothes for skinny and beautiful people.

Way to alienate shoppers of all kinds -- big, small, Swift-loving and beyond.
