When she changed her hairstyle, Aaliyah took her mother's advice and covered her left eye, much like Veronica Lake. The look has become known as her signature and been referred to as fusion of "unnerving emotional honesty" and "a sense of mystique". In 1998, she hired a personal trainer to keep in shape, and exercised five days a week and ate diet foods. Aaliyah was praised for her "clean-cut image" and "moral values". Robert Christgau of "The Village Voice" wrote of Aaliyah's artistry and image, "she was lithe and dulcet in a way that signified neither jailbait nor hottie—an ingenue whose selling point was sincerity, not innocence and the obverse it implies."
