Dahl did not experience a smooth start in the rigid world of fashion. Her size became an immediate issue, as the clothes she was appointed to model were not made to fit her frame. An initial shoot with Vogue featured her in an ensemble by Gianfranco Ferré that had to be pinned together in order to hold. Subsequent work was often done in the flesh, such as the 1999 Pirelli calendar and an infamous ad for Opium perfume. The latter was a major boost to her career, as the controversial shot of a naked Dahl caused a stir in Britain and received an inordinate amount of complaints from the public. The campaign from Yves Saint Laurent was pulled but not before Dahl had become somewhat of a celebrity for her unconventional beauty.
