Kourtney Kardashian and Mason Play in Paris.

Celebrity Fashion & Style - Keeping up with the Kardashians' star Kourtney Kardashian keeps kids looking cute with the help of some designer duds.

The beautiful new mom dresses her children in Stella McCartney.

The reality TV star - who has kids Mason, two, and four-month-old Penelope with partner Scott Disick - is a big fan of the British designer and loves her ''cute'' childrenswear.

Kourtney said: ''Stella is my favorite designer for Penelope. Even Mason has the pajamas - they're so cute.''

Kourtney's sister Kim is also a big fan of Stella for her own wardrobe.

She said: ''I love British designers. I'm a big fan of Stella McCartney and Sarah Burton.''

Meanwhile, Khloe Kardashian refers the style of Rihanna and Victoria Beckham, but would never try to copy someone else's look.

She said: ''I like to take inspiration, not dress head-to-toe like someone else. I'd look crazy if I was walking around looking like Rihanna, because I'm not a rockstar.''

Kourtney, Kim, and Khloe recently launched their Kardashian Kollection fashion range, after teaming up with British high street store Dorothy Perkins.
