Willow, 13, feels that her fashion sense is influenced by her personality, reported Contactmusic.
"My whole family, we love Cartier," she said.
However, despite being from a superstar family, she also likes to shop in budget stores and at flea markets.
In addition to her distinctive style, Willow also likes to experiment with her hair, having dyed it green and pink before recently opting for a bleached blonde.
"My hair is super, super, super, superhard to destroy. It's a survivor," she added.
