The characters in AMERICAN PSYCHO are captive to 1987 fashion, which costume designer Isis Mussenden describes as "much bigger than now -- shoulders with lots of pads, big glasses, big earrings and necklaces, and clothes that used large quantities of fabric. It's a general rule of thumb that when times are affluent, the clothing becomes voluminous." Mussenden's challenge was threefold. "As a costume designer, my first job is to interpret the script and build characters off the clothes," she says. "Clothing not only conveys character and mood visually, it also tells the story. When Bateman is feeling powerful, he wears a red tie, a shirt with bold stripes. But in weaker moments he appears in a lighter suit and a less flattering yellow tie.
