Kourtney Kardashian flashes her toned legs in a sizzling trench coat dress during recent appearance

Kourtney might be the eldest Kardashian sibling, but it surely doesn't seem like it as she can pull off almost anything she wears looking like a teenager.

Last Wednesday, Kourt chose to step out in a leather trench coat that showcased her legs as she brought her son Mason, 8, to his art class.

The 'Keeping Up With The Kardashians' star showcased her very thin waist in a sexy jacket while highlighting her perfectly toned legs which she accented with ankle boots.

Her hair was parted down at the center, and she accessorized her look with a pair of trendy sunnies.

Mason on the otherhand, walked alongside his beautiful mother wearing a graphic t-shirt, trousers, and sneakers.

For those wondering how Kourtney has managed to keep up her great body, she confided on her website:

"I try to eat healthy and include as many organic whole foods as possible."

Before eating, Kourtney confesses to taking collagen supplements on an empty stomach. She then swallows the tablets using water mixed with a tablespoon of organic apple cider vinegar, which she explains have very good health benefits.

"Both of these habits have tons of health benefits that affect everything from your skin to the way your body processes nutrients."
