Victoria was present at Vogue Festival this year and having just watched the interview, I highly recommend you do to. It is a great chance to see Victoria in a very natural light as a working mother, pursuing a career she is passionate about.
You may feel that her opportunity in fashion stemmed from her popularity from THE greatest band of all time, The Spice Girls, but like any career prospect or career overhaul, Victoria works hard, getting involved in every aspect of being a designer and brand, an expert in her field which helped her drive to be the successful designer she is today with a number of raised (or as she puts it 'or those that could') eyebrows along the way.
