Boys and their toys: Rachel Zoe's son Skyler only has eyes for model cars when she tries to take him hat shopping

Yesterday she previewed her fall collection at Vancouver's Holt Renfrew store.

But today celebrity stylist Rachel Zoe was back in Los Angeles attempting to style her favourite client - her 17-month-old son Skyler Berman.

The 40-year-old fashion designer tried three different trilby hats on her gorgeous toddler, but little Skyler was far more interested in playing with toy cars than headwear.

The skinny stylist, wearing her trademark bug-eyed sunglasses, strolled down Robertson Avenue towards Kitson in gargantuan strappy platforms and ditched her usual maxi-dress for a belted black dress over a pair of matching jodhpurs.

Meanwhile, her equally fashionable little man wore a periwinkle-striped tank top and matching trousers with tan brogues and his usual fashion staple - a trendy amber teething necklace.

However, Skyler looked happier with his luscious brown locks uncovered and focused all of his toddler attention on several toy cars, eventually leaving with two tiny vehicles as they exited.

Despite being carried into Kitson wearing a straw hat with a periwinkle band, Rachel eventually opted for her son to wear his new denim-coloured fedora, which matched his beautiful baby blues, out of the trendy West Hollywood shop.

Skyler didn't become one of Hollywood's most stylish toddlers because of genetics.

The stylist-turned-designer once told InStyle magazine that her son is her favourite person to style because he has 'no opinion' on the hundreds of designer outfits she puts on him, unlike her clientele of A-list divas.

'Every minute I have to buy things for my son,' the notoriously skinny fashionista said. 'It is too much fun. It is like dressing a live doll. He has no opinion.'

Zoe, whose clients include Jennifer Garner, Kate Hudson, and Cameron Diaz, has admitted to spending $90,000 on fitting out her son's nursery and inside his wardrobe you will find over 22 pairs of shoes, including $277 Hermés boots, $150 Tod's loafers.

The Rachel Zoe Project star is right in the thick of showcasing her new collection all over the U.S. and Canada.

For autumn, the designer used feminine prints to create maxi dresses as well as a magenta blazer and sequined cocktail dresses, capes, and riding boots.

A few hundred excitable Canadian guests attended the collection preview yesterday, where she revealed that she considers her life to be boring despite capturing the attention of fashion lovers everywhere.

'I'm really not very interesting,' she told The Province. 'I've been with the same man for 21 years, I like to get into bed at 10 o'clock at night. I work all day and I'm with my son every minute and that's my life.'

Expensive tastes: Yesterday the stylist-turned-designer previewed her fall collection at Vancouver's Holt Renfrew store with prices ranging $175 to $895
