Style icon Kate Middleton might regret one particular fashion choice, which has spawned a fur fight between PETA and the International Fur Trade Federation.

A photo of Kate Middleton was posted on the IFTF's Web site under a caption hailing the Duchess for wearing a classy fur-lined coat, reported The Hollywood Reporter.

People for the Ethical Treatment of Animals (PETA) was enraged by the posting and told the IFTF to remove the photo.

PETA claimed that it checked with Middleton's representatives and discovered that the coat was, in fact, lined with faux fur.

The Duchess' office has confirmed in a letter to Peta that 'Her Royal Highness was not wearing fur. The coat was not lined with fur.' We therefore insist that you remove the photo from your social media page and issue an immediate public retraction of your claim, read the letter from PETA to the IFTF.

To state that the Duchess is wearing fur is not only false but offensive...to portray the new Duchess wearing something so blatantly cruel and contrary to her country's values is insulting.

PETA has reportedly threatened legal action against the IFTF, according to THR, but the IFTF has not yet responded.

As both a royal figure and a style icon, Kate Middleton is looked at and admired by millions of women around the world. In the fight against fur, Middleton surely can pose as a threat or an ally to PETA.

It is unclear whether the 30-year-old beauty is for or against the use of fur, but what is known is that she is an animal lover. Middleton and husband Prince William recently got their first puppy, a black Cocker Spaniel named Lupo. Lupo is the son of Middleton's mother's dog.
