A Caitlyn Jenner costume for sale on Amazon has sparked outrage in transgender groups who call the costume transphobic.The costume is titled “Bruce Caitlyn Jenner Olympian I Am Cait Adult Costume” and is modeled from Jenner’s winning uniform from the 1976 Summer Olympics.

Pieces from the costume include a Jersey tank featuring Jenner’s 935 number, blue shorts, a brunette wig and two plastic “Olympic” medals.

“Show your love for Caitlyn Jenner with this awesome adult costume,” reads the product’s description.

Jane Hamlin, president of transgender support group the Beaumont Society, called the item “transphobic” in a statement obtained by Yahoo News.

“I am astonished that a transphobic costume mocking Caitlyn Jenner is being marketed in the way it is. It is completely tasteless,” Hamlin said.“The transgender community has been getting quite a battering in the media recently because we would like to have autonomy over our own identities. We have become accustomed to insensitive mockery, but had hoped that cisgender people had become tired of such stunts and realized that it is not funny.No one chooses to be trans. It is the way we are born, it is who we are.”

Transgender charity Stonewall also criticized the costume and asked for it to be “taken off the shelves.”

“This is a reminder of how much is left to do to combat the abuse trans people face every day. This costume reduces a marginalized group to the butt of a joke,” a spokesperson said.

eBay did also sell the costume but after facing backlash online, the website removed it.

According to TMZ, Costume Agent, the costume’s manufacturer, refuses to pull the item. A rep said “It’s a costume. It’s funny.”
