The reality star and her one-year-old stepped out in LA on Wednesday afternoon (25 September) to visit the Kardashian sisters' DASH clothing store and of course, they were both dressed to impress.
34-year-old Kourtney proved her fashionista credentials in a silk pyjama-style top and matching bottoms, which featured a navy blue and green print.
She teamed the ensemble with nude heels and a co-ordinating handbag, while shielding her eyes from the LA sun with a pair of circular framed sunglasses.
Meanwhile, little Penelope also looked trendy in a cute floral print onesie and a bright pink turban - a head accessory favoured by her famous mum.
Kourtney has been seen sporting similar turban headgear on a number of occasions recently, so it's almost no surprise that she has passed this new fashion on to her daughter.
The mother-of-two often dresses her children (including 3-year-old son Mason) in the latest styles and isn't afraid to experiment with kids clothing - although some people have considered her outfit choices a bit too mature.
Earlier this year, Kourtney was seen on a family day out at a swimming pool, where she dressed Penelope in a leopard print bikini.
During her outing yesterday, Kourtney was joined by younger sister Khloe, who appeared to be keeping a low profile.
The yummy mummy also spent time with sister and fellow mother Kim earlier this week, as the pair headed to a business meeting.
We wonder whether Kourtney will be lending Penelope's turban to little North West?
