Schiffer has also been the face of Spanish clothes store, Mango and Accessorize, where she had her ears pierced especially for her Autumn/Winter 2006 Accessorize advertising campaign in 2006. Schiffer still holds a contract with L'Oréal and Ebel watches, and her billboard picture for Kenar has also hung over millions of tourists at Times Square. Since 1990, she has created a swimsuit calendar each year which she stars in and designs herself.
Schiffer later appeared in advertisements for Pepsi, and has danced with a cartoon version of Mickey Mouse in advertisements promoting Fanta for an estimated $2 million. From her appearances in a 1998 Citroën advertisement, she earned a reputed £3 million. Karl Lagerfeld filmed her for a Dom Perignon campaign, some ten years after her first appearances in Chanel adverts.
She is signed to several agencies, including 1/One Management in New York City, Simon Fuller's 19 Entertainment in London for her non modelling interests, and her mother agency 'Model Management' in Hamburg.
