Tchoumitcheva began modelling at the age of 12, and became famous in her hometown. When she entered the national "Miss Switzerland" pageant in 2006, she was judged as both 1st runner-up and Miss Photogenic. It stirred up a national controversy. For the first time in history, the Miss Switzerland organization took the unprecedented step of offering Tchoumitcheva an appearance contract similar to that of the winner. After the contest she was considered the "most eligible single woman in Switzerland". In May 2009 she was elected as the Best Bikini Body, according to a survey by the magazine Schweizer Illustrierte. In 2012 she was featured with a photoshoot and personal interview in the Spanish GQ magazine.
