The `Somewhere` director - who has also worked as a model, photographer and TV presenter - is surprised when people cite her as a fashion inspiration and never thinks of herself in that way.
She said: "I don`t think of myself in the way I think of Tina Chow or Diana Vreeland or someone I thought was stylish when I was a kid. I just don`t think about it."
However Sofia - who has also designed a line of bags for Louis Vuitton with her close friend Marc Jacobs - admitted she does love "beautiful things".
She added to Britain`s Vogue magazine: "I like beautiful things. I like photography, well-made clothes. I appreciate creativity. I tend to like things that are more simple and classic. Not super-glitzy, I guess. I wouldn`t describe my aesthetic as bling."
While Sofia`s own style may be revered, she tries not to impose her classic look on her four-year-old daughter Romy.
Sofia - who also has a five-month-old daughter Cosima with her boyfriend Thomas Mars - said: "I`m just thinking about how my four-year-old is really into pink and purple and sparkles right now and I don`t want to inhibit her by forcing navy-blue clothes on her.
"I have to not be a snob when it comes to toddlers."
