Petra was born in Manchester, UK. An only child, Petra was spoiled in her youth, Petra often even wearing a tiara at home and declaring herself to be a true princess. At school Petra did face bullying over her attitude but her confidence and ability to stab people in the back helped her survive, often seeing her build up friendships to only in turn end them when it suited her. There were many controversies over Petra's public educational career, including accusations of flat-out not doing a project, but she was able to convince her teacher that it had been stolen instead and received a typical grade expected of her. For education after school Petra attended the University of East London, studying fashion.
After finishing university Petra went to work for a fashion magazine, soon befriending fellow writer Sharon Wilcox. The two worked together for a few years, later talking about starting their own website. Petra loved the idea, but while Sharon worked on courting Heather Prescott for their cause Petra secretly went to investors, passing off Sharon's ideas as her own, and was soon setting up Senfashional back in Manchester before Sharon had realized what happened. Eager to keep Sharon from surpassing her, Petra soon began to ruthlessly undermine FashionZeit, Sharon's own site, stealing away talent, undercutting their prices and even going so far as to plant itching powder in the clothes of hired models.
