Answer by taking a quote from the following article:

Beckham was born at the Princess Alexandra Hospital in Harlow, Essex, United Kingdom, and raised in Goffs Oak, Hertfordshire. She is the eldest of three children of Jacqueline Doreen (nee Cannon), a former insurance clerk and hairdresser, and Anthony William Adams, who worked as an electronics engineer. They founded an electronics wholesale business which allowed a comfortable upbringing for Victoria, her sister, Louise, and her brother, Christian Adams. Beckham's great-great-great-grandfather was German artist and revolutionary Carl Heinrich Pfander.

Beckham made a guest appearance on the catwalk for Maria Grachvogel on 17 February 2000, marking her debut as a model at London Fashion Week. Beckham also acted as a British ambassador for Dolce and Gabbana and was briefly the face of Rocawear in 2003. Beckham designed a limited-edition fashion line for Rock & Republic called VB Rocks in 2004, consisting mainly of jeans for the high end of the market, retailing at approximately $300 in the US. On 16 January 2006, Beckham walked the runway for Roberto Cavalli at Milan Fashion Week, and was for a period exclusively dressed by him for red-carpet and social events. For the March 2006 issue of Harper's Bazaar, Beckham acted as fashion editor when she styled her close friend, Katie Holmes, for a fashion shoot. She has admitted to a personal love of sunglasses, saying "I'm quite obsessed with sunglasses. I collect vintage Guccis and Carreras - they can make virtually any outfit look cool." After Beckham's departure from Rock & Republic, in September 2006, she furthered her fashion ventures by launching her own denim label, dvb Style. Beckham then launched a new official website, dvbstyle.com to promote her fashion work. On 14 June 2007, Beckham launched dvb Denim collection in New York at Saks Fifth Avenue, along with unveiling her eyewear range in the United States for the first time. In the same month, Beckham made her first appearance at London's annual Graduate Fashion Week as a judge alongside Glenda Bailey (editor-in-chief of Harper's Bazaar) and Lanvin's Alber Elbaz, to choose the winner of the River Island Gold Award, worth PS20,000. In August 2007, Intimately Beckham perfume was launched into US stores, one of more than 20 perfumes she and David Beckham have introduced over the years. In September 2007 her cosmetics line V-Sculpt was launched in Tokyo. In a 2007 appearance at an LA Galaxy press conference, Beckham is credited with having popularised Roland Mouret's 'moon dress' and his brand, and Beckham was also the face of Marc Jacobs for his Spring 2008 collection. Beckham has graced countless fashion magazine covers during her career, including I-D in 2004 and W in 2007. Her first Vogue appearance was the April 2008 British edition.
