Jazz is an honourary cofounder of the TransKids Purple Rainbow Foundation, which she and her parents founded in 2007 to help assist transgender youth. In 2013, she also founded Purple Rainbow Tails, a company that allowed Jazz to sell rubber mermaid tails in order to raise money. While chatting with Dazed, Jazz explained that her fascination with mermaids began when she was a kid.
"It's actually very interesting because a lot of transgender people gravitate towards mermaids, and they say it's because they have no genitals — so it's like wow, mermaid, cool, nothing below the waist, just a beautiful tail," she said. "For me it was an attraction right from the start. I would have dreams about being a mermaid, so I decided to become one — I created this silicone mermaid tail when I was 12 and then I started making more of them. They were cool [and] I started selling them!"
