Stealing the show! Rachel Zoe dresses youngest son Kaius Jagger in a jaunty hat as she takes him to NYFW

There's little doubt she left no detail untouched for her latest presentation.

But Rachel Zoe was nearly upstaged at her own fashion show by her stylish son Kaius Jagger, 21 months, who proved good sartorial sense runs in the family with his straw fedora and preppy onesie.

The 44-year-old was head turning in her own right with a pristine monochrome jacket and black platform heels as she posed with her youngest during her line's spring/summer runway show at New York Fashion Week on Sunday.

Rachel was styled to perfection as usual.

The former Bravo reality star wore her golden locks down in a glossy hairdo, with a soft wave adding a bit of volume to the style. 

She flattered her famous face with dark and blossoming lashes, and added a pop of colour with her full strawberry red lips.

Rachel, who is known for popularizing the so-called boho-chic look, launched her namesake line in 2011. 

The former star of the Rachel Zoe Project has been in the fashion industry for 20 years and has been the stylist for Hollywood stars such as Jennifer Lawrence and Anne Hathaway. 

Sunday's show was a perfect display of Rachel's signature bohemian touch, with loose-fitting white dresses and summery off-the-shoulder numbers exhibited on the runway.

Meanwhile, the fashion darling is in the middle of a career transformation, several years following the cancellation of her Bravo reality show, The Rachel Zoe Project.

Rachel will star in a new weekly talk show with her husband Rodger, which will premiere on Lifetime on September 24 in the US.

The show, called Fashionably Late With Rachel Zoe, will also star fashion editor and renowned celebrity pal Derek Blasberg.
