A video of the attack, shared on Twitter by Stop Homophobie, has been viewed over two million times and started a dialogue over transphobic attitudes in France.
"For once, there is a video that lets us see how trans people are treated on a daily basis," says campaign group SOS Transphobie.
"Trans people are not taken seriously or often the blame is placed on them because they are trans," SOS Transphobie said.
The 31-year-old victim has not shied away from the media following the attack.
"If I am doing this media marathon, it is to increase the visibility of transphobic attacks more than anything else, " Julia - who asked that her full name not be used - told French publication Libération.
"It is also to show those ignorant people that I will come out of this experience with my head high," she added.
Paris prosecutors are treating the attack as driven by gender identity and sexual orientation, the BBC said.
The assault sparked outrage on social media, with the minister for gender equality, Marlène Schiappa, tweeting: "This clearly transphobic attack in the heart of Paris is unacceptable."
"LGBT+ phobic attitudes are not opinions but come from stupidity and hate," Ms Schiappa said.
