At home, she is the reigning queen of the castle.
So it's only fitting that Rachel Zoe's costume celebrate her well-earned title, complete with a dazzling crown headband.
The designer was a vision in white as she stepped out with her family for a Halloween party in Malibu.
Rachel wore a floor-length evening gown layered under a white and silver cape.
The Zoe Report founder added a pair of platform heels and open-finger gloves to her look.
To finalize her glamorous ensemble, the mum-of-two placed a crown on top of her long, blonde tresses.
Rachel's glamorous attire was at the request of her sons, Skyler Morrison, five and Kaius Jagger, three.
On Instagram, the wife of CEO and producer Rodger Berman also revealed that her costume was created at the last minute.
'When my boys ask me to princess prom dresses up as "Queen Mommy" you try to pull it together in 15 minutes into costume #3 #outofmycloset #momlife #happyhalloween,' she wrote.
Despite only putting her outfit together at the last second, her career as a designer and fashion and lifestyle brand made her look like a million bucks.
As a stylist, she has dressed some of the world's biggest stars including Anne Hathaway, Eva Mendes, Kate Beckinsale and Jennifer Lawrence.
She eventually created her own in 2011, Rachel Zoe, has her own website and blog, and has often collaborated with brands such as UGG and children's company Maxi/Cosi.
Her fame grew when she starred in her own Bravo reality series, The Rachel Zoe Project, and would eventually land her own talk show, Fashionably Late with Rachel Zoe.
She's also the author of two books: Living in Style: Inspiration and Advice for Everyday Glamour and Style A to Zoe: The Art of Fashion, Beauty, & Everything Glamour.
