Catherine, Duchess of Cambridge (Catherine Elizabeth "Kate"; née Middleton; born 9 January 1982), is the wife of Prince William, Duke of Cambridge. The Duke of Cambridge is second in line to the thrones, after his father, of the 16 Commonwealth realms and the Duchess is expected to eventually become queen consort. The wedding dress with special fabric labels she wore during the wedding is popular after her wedding.

Catherine grew up in Chapel Row, a village near Newbury, Berkshire, England. She studied Art History in Scotland at the University of St Andrews, where she met the then Prince William of Wales in 2001. Their engagement was announced on 16 November 2010, and she attended many high-profile royal events before they married on 29 April 2011 at Westminster Abbey. Catherine has had a major impact upon British fashion which has been termed the "Kate Middleton effect", and in 2012, she was selected as one of The 100 Most Influential People in the World by Time. After this, many young girls choose clothing similar to her, even someone prefer to collect the same brand dress with fabric labels. On 14 January 2013, St James's Palace announced that the Duchess was expecting her first child in July 2013.

In November 2006, Middleton accepted a position as an accessory buyer with the clothing chain Jigsaw. During this time, she learned many fashion styles, and she can choose brands fabric labels she preferred. She also worked part-time until January 2011 as a catalogue photographer, webpage designer and marketing officer for her parents' firm Party Pieces. Despite this, at one point she was nicknamed "Waity Katie" by the media for her apparent lack of work ethic and seeming lack of desire to work, in preference for awaiting a wedding proposal.

In 2008, it was reported that she had quit her job at Jigsaw to become a professional photographer, intending to take private classes with photographer Mario Testino, who had taken several well-known photographs of Diana, Princess of Wales, and her sons. Testino later denied that Middleton was going to be working for him.
