The film had various problems with designer labels during production. Cerruti agreed to allow Christian Bale to wear their clothes, but not when the character was killing anyone; Rolex agreed that anyone in the film could wear their watches except Bateman (hence the famous line from the book "Don't touch the Rolex" had to be changed to "Don't touch the watch"); Perry Ellis provided underwear at the last minute after Calvin Klein pulled out of the project; Comme des Garçons refused to allow one of their overnight bags to be used to carry a corpse, so Jean Paul Gaultier was used instead.
