Enjoying a weekday playdate, Kourtney Kardashian and her two children left a friend's house in Los Angeles on Thursday (January 17).

The eldest Kardashian sister looked pretty in a cleavage-baring black top, matching jacket and leggings as she toted little Mason on her hip before coming back for baby Penelope.

Though she may be busy corralling the kiddies from coast to coast, the 33-year-old mother-of-two still maintains a fashion sense.

On Wednesday, Kourt shared one of her go-to wardrobe items on her blog, posting, "If there’s one item I can’t live without this spring it’s a great denim shirt! It’s a chic alternative to a cardigan or sweatshirt and literally goes with anything… black jeans, leggings, even tucked into a pencil skirt."

The E! stylista added, "You can also layer it over a cute cami top or t-shirt. So easy to just throw on and always in style!"
