Ann Demeulemeester (born 1959, Waregem, Belgium) is an influential fashion designer whose clothing is usually displayed during Paris Fashion Week.
She studied fashion design at the Royal Academy of Fine Arts in Antwerp from 1978 to 1981. As a result, she is often referred to as a member of the 'Antwerp Six', the radical - but all distinctive - Belgian designers of the 1980s.
She is married to photographer Patrick Robyn and has a son, jethro. The couple live in Belgium's only Le Corbusier house situated in Antwerp.
Ann Demeulemeester has worked with the artist Jim Dine, and has also been associated with Patti Smith. Currently, she is working on a clothing line inspired by Jackson Pollock.
