Early work and controversy (2007–08) Jagaciak's modeling career began in 2007 after she was encouraged by her sister to attend an open casting of GAGA Models Agency at a shopping center in Poland. She was then picked up by
IMG who signed her and in July 2007 she appeared on the cover of French
Jalouse. Her big break came at age 13, In May 2008, she appeared for the second time on the cover of French
Jalouse, and in October 2008 Jagaciak also landed covers for Japanese ''
Harper's Bazaar, and Japanese Spur''. After getting some criticisms about
sexualization of young models in the fashion industry, organizers of Australian Fashion Week ruled that all children under 16 years old be banned from walking at the shows in Sydney. Jagaciak, who felt she was old enough, thought the decision was "stupid". Her mother, Marlena, said she accompanied her daughter on assignments and would never put her in danger. Jagaciak's mother believes her daughter has enough support to handle the tough
industry but does not resent Australia's ban. She became known for her powerful runway walk – even though she fell on the
Hervé Léger runway, she went on to close both
Shiatzy Chen,
Marc Jacobs and
Marni. She has gone on to walk in
Milan too, walking for
Prada,
Dolce & Gabbana,
Fendi, and
Versace, but she didn't meet the age requirement to walk in the
Paris Fashion Week. As of May 2009, she had been on 13 magazine covers. Designer
Francisco Costa said of her when she became the face of
Calvin Klein, "She possesses a timeless beauty that gives her the ability to be highly versatile, making her one of the most promising new models today." However, her contract with
Calvin Klein ended for the Fall/Winter 2010 season, and Jagaciak was subsequently replaced by Dutch model
Lara Stone.When she was in the spring 2011 "New York Fashion Week's Top Ten Models" list at No. 7 opening for
Tommy Hilfiger and closing shows for
Derek Lam,
Richard Chai LOVE. In 2010, she signed an exclusive contract with Chanel and became the face of Chanel makeup, in a large number of campaigns, most of them photographed by Norwegian photographer Solve Sundsbo. She worked for Chanel until the early 2020s. In 2015, she became a
Victoria's Secret Angel. The next year she left the brand. Jagaciak took a two-year hiatus to be educated at
School of the Art Institute of Chicago. ==Personal life==
