"I hope Villainesse will empower, encourage and inspire the women who write for and read it. My vision is for Villainesse to grow to be both a vibrant and supportive community and an outlet where ethical, truthful media is prioritised. As a young woman, I don't want to be preached to, patronised or misled. I feel like we're in the middle of a wave of modern 'girl-power' and I very much hope Villainesse will play a part in that."
Marvelly said she believed the word feminism got "a bad rap".
"Let's be clear " feminism means equality.
"Recently we've witnessed a reclaiming of the term 'feminist'. In a world where women are still paid less than men for the same jobs, where only 4.6 per cent of Fortune 500 CEOs are women and none of the NZX50 companies have female CEOs; where girls in the developing world are often excluded from education, and where a survivor in the Roast Busters investigation can be questioned about what she was wearing, feminism is as relevant and vital as it always has been.
"It's heartening for me to see widespread dismantling of the myths surrounding feminism. I hope that Villainesse can join the fray, stand for equality and become a part of the modern feminist movement."
Marvelly has attracted more than 50 women from New Zealand and around the world to contribute to her website, including nanophysicist Michelle Dickinson and MPs Nikki Kaye and Jacinda Ardern.
TV host and artist Erin Simpson is also a contributor.
"Villainesse's content is put together by a group of women who have an opinion and give a damn, it can only be successful. It's a privilege to be part of Villainesse. I hope to continue to help and add value."
While Villainesse.com is Marvelly's main focus, she continues to write music and has projects to be released later this year. Her pop song Collisions was recently named a semi-finalist in this year's International Songwriting Competition.
