Jessica Simpson

The singer-and-actress says it's important not to dress to over-the-top as she doesn't want people to think she's not approachable.

Speaking as the Guest Editor for women's website iVillage, the mother-of-one said of her look: "I would say that I'm pretty casual. I don't ever wanna come across too intimidating, so as long as I look like you can come up and give me a hug, that's good.

"My signature look has always been really classic and comfortable jeans and T-shirt."

The blonde beauty also revealed her mother, Tina, is her style icon as she's just so creative with what she wears.

She said: "My style icon really for my whole life has been my mother. The way she can put together and outfit and just color and even print mixing. I mean she's just so creative and has always looked flawless to me. That's why she runs (my clothing range) the Jessica Simpson collection. I trust her with every single garment."
