Cool mom! Alessandra Ambrosio shows off her effortless style in all-black as she takes son Noah to school

As a Victoria's Secret Angel who spends much of her time jetting around the world, Alessandra Ambrosio can often be found in a bikini.

But the 35-year-old showed that she can just as easily nail autumn style on Friday.

Alessandra was seen covered up in head-to-toe black as she was spotted walking her four-year-old son, Noah, to school in Los Angeles.

Alessandra dressed for the cooler temperatures on the overcast Southern California day. 

Her lithe silhouette was swallowed up by a trendy long-sleeved tunic sweater which featured a longer dark plaid blouse layered underneath. 

She teamed the effortlessly chic look with a pair of skintight black leggings.

The five-foot-ten bombshell added a sexy pair of black thigh-high boots which featured a small block heel.

Get supermodel style in Alessandra's Valentino boots

'tis the season to wear over the knee boots. Yes, winter is back and we're bringing those bad boy thigh highs back out again this year.

Alessandra Ambrosio was a reason all by herself to secure the return of last winter's hottest shoe trend. Over-the-knee boots are a must.

They look great with skirts, dresses, tight and jeans and you just cannot go wrong when they're in a versatile shade of noir. Up the ante with a luxurious suede finish and you've simply nailed it just like Alessandra in her Valentino pair.

They're a little on the pricey side at well over $1k, but we think they're totally worth it. We love the subtle heel that makes them walkable but also dressy (or perhaps just an easy way to do-up up your jeans and tee for daytime?). Click right to snap them up.

If you're thinking they're a little out of your budget then head below for a line up cheaper booties to get the look for less.

Alessandra left her long locks down and topped off the look with a chic wide-brimmed hat and over-sized shades.  

The brunette beauty appeared in good spirits as she dropped of her youngest child at school. 

Alessandra's look-alike daughter, Anja, who is eight-years-old, wasn't seen on the outing.

The Brazilian bombshell held on tight to her little blonde boy, who was also dressed for the cooler temperatures and prepared for the rare chance of rain.

Noah sported a blue green rain jacket, navy sweat pants, and black rain boots, and tried to keep up with his famous mom's stride while he held onto a toy helicopter and rolled his backpack behind him.  

In just a month's time Alessandra will be stripping to her underwear and storming the catwalk while filming the Victoria's Secret Fashion Show that is going to take place in Paris.
