Dekkers studied at the art school in Breda, graduating cum laude in 1991, and two years later launched her first Undressed collection with the aid of a government grant. The work was received as a fresh take on lingerie design and grew into a full house of fashion lines.
The marlies|dekkers brand now runs stores worldwide in cities including Amsterdam, Rotterdam, Antwerp, Paris, Berlin, Moscow and Bangkok, alongside online sales. Dekkers has been named ELLE's Innovator of the Year and won the Prix Veuve Clicquot Business Woman of the Year in 2007; her work is held in the Rijksmuseum Amsterdam.
