I don't think there's any celebrity who has cleaned up better than Nicole Richie. Remember The Simple Life? (I watched every single episode.) She was a riot, and a bit of a liability. Since then, she has pulled herself together nicely and transformed into a fabulous designer, not to mention an even more fabulous mom. After creating her jewelry line, House of Harlow 1960, named after her daughter, Richie also developed a chic maternity line and a shoe collection--all of which are affordable to non-celebs!

With such a busy life, and now, with two kids in tow, Richie manages to balance it all while staying in style. Her wardrobe staples and go-to pieces are practical, easy and gorgeous. From maxi dresses to oversized cardigans, from fitted blazers to flat leather boots, moms and non-moms can learn a style lesson or two from her.

Shop her jewelry line now at Bebe.com. Pieces start at $38.
