This is the real Piper and Larry…

It’s based on a true story.
Orange Is the New Black is based on the memoir of the same name, written by Piper Kerman. Kerman wrote about her time spent in prison after she was locked up for laundering drug money, and the show borrows heavily from her experiences. The writers veer off in their own narrative directions, of course, but knowing that the fiction of Litchfield Prison draws on fact just makes the show all that more compelling.
Those are real inmates in the opening credits.
The costumes are completely authentic.
The costume designers did extensive research to make sure the characters’ clothes look as realistic as possible. And to truly up the realism factor, they use actual inmate apparel, from the khaki prison scrubs to the officer uniforms. Even the bras and granny panties you see on the show are bought through prison suppliers!
Mendez’s mustache, sadly, is NOT authentic.
