A supermodel is a highly paid fashion model who has a worldwide reputation and background in haute couture and commercial modeling. The term became popular in the 1990s. Supermodels usually work for prominent fashion designers and clothing brands. They may have multimillion-dollar contracts, endorsements, and campaigns. Supermodels have branded themselves as household names and worldwide recognition is associated with their modeling careers. They have been on the covers of leading fashion magazines. Claudia Schiffer stated in 2007 that, "In order to become a supermodel one must be on all the covers all over the world at the same time so that people can recognise the girls."
