Fans are really not happy with this Caitlyn Jenner Halloween costume

When Caitlyn Jenner introduced herself to the world as a woman, she did so on the iconic cover of Vanity Fair.

It is a photoshoot which has now been seen by people all over the world. 

And now an American costume company has began selling a Caitlyn Jenner outfit which is inspired by the Vanity Fair cover.

However, the Halloween attire has caused serious outrage online, with fans of Caitlyn branding it as "disgusting". 

The websites Spirit Halloween and Anytime Costumes posted the costumes on their websites, but both have received backlash, with some people suggesting that the unisex outfit is offensive to the transgender star. 

Lisa Barr, senior director of marketing at Spirit Halloween, said: "At Spirit Halloween, we create a wide range of costumes that are often based upon celebrities, public figures, heroes and superheroes."

"We feel that Caitlyn Jenner is all of the above and that she should be celebrated. The Caitlyn Jenner costume reflects just that."

Transgender activists have even launched a petition on Change.org asking the companies to stop selling the costume, which is priced at €68. 

As an alternative, there is also an Olympic-style option which recreates the former Bruce Jenner's gold medal-winning moment with a red top and blue shorts.
