Havana good time? Smiling Kourtney Kardashian is leggy in a pinafore dress as she balances Mason and Penelope in Cuba

It was a night out for the yummy mummies on Thursday as Kourtney Kardashian took her two eldest children out with sister Kim and her daughter in Cuba.

The 37-year-old balanced her three-year-old daughter Penelope on one hip, while clinging to her eldest son Mason, six, all the while looking youthful in a pinafore dress.

Proving that the Keeping Up With The Kardashians crowd are enjoying their time in Havana, Kourtney smiled as she followed Kim and North West to one of their flashy fuchsia cars.

Style up some suede in a dress by Jitrois

Cute dress alert! Cute dress alert!

Kim Kardashian may have been turning heads with her incredible curves while out in Havana last night but it was Kourtney Kardashian's dress that got us hot under the collar. We love it so much we're not sure what to do with ourselves.

This little beauty is by French label Jitrois and well, where do we start? The super soft suede is to die for, the adorable pinafore style is flirty and preppy, and the perforated wide box pleats are the pièce de résistance. All in all, this is one fantastic dress.

The good news is it's available to buy at Stylebop now. The bad news is it will set you back $3100. So if you're feeling flush then click (right) to add it to your new season wardrobe. If like us, that price tag is a little out of reach, then head to our edit below for more affordable versions of the look.

Go faux at Boohoo and Prettylittlething.com or get the real deal by Monki at ASOS and Capulet at Shopbop. Style with a red lip and sandals this summer, layering a white tee underneath on chillier evenings.

Kourtney, who also has one-year-old son Reign with Mason and Penelope's father Scott Disick, put on a leggy display in the top-to-toe tan ensemble.

With a hemline that kicked up at the thighs, the brunette added strappy sandals and a tiny coin purse to the look.

The mum-of-three completed the image with a scarlet lipstick and a high ponytail that left her long, raven mane swinging behind her shoulders.

The children were kitted out in contrasting charcoal ensembles; Penelope in a pretty day dress and Mason looking cool in shorts and a vest.

It was a girls' night for busy mums Kourtney and Kim, who appeared to be on their own with their children that evening.

Kim's husband Kanye West - with whom she has new son Saint - was noticeably absent, as well as Kourtney's ex Scott, who has not joined the famous family on their trip.

Youngest sister Khloe has come along for KUWTK filming, also lending a hand when it comes to looking after the youngest Kardashians.

Not a family to go quietly, the group have been travelling around communist-led island in the back of bright pink convertible cars.

The celebrity sisters are filming season 13 of their reality TV show after first spending time in Miami, Florida.
