Kim and Kourtney Kardashian have taken their curves to Cuba!

The reality TV stars landed in Havana on Wednesday, just months after a travel ban to the country was lifted, and have been flaunting their slimmer figures ever since. On Thursday, the sisters naturally turned a playground into a sexy photoshoot while posing for photographers in a park.

Kim stepped out in an all-white ensemble, while Kourtney played up her look with an oversized statement necklace, edgy leather shorts and a white tank top.

The girls continued their adventures by hopping into a bright pink, vintage convertible as they cruised around Cuba with Kim's husband, Kanye West.

Kim, who has been very vocal about her weight loss journey since giving birth to her and Kanye's second child, Saint, in December, rocked a skintight little black dress that perfectly showed off her fit post-baby body while heading to dinner. She accessorized with black heels and a chunky choker that was given to her mom, Kris Jenner, by the late Nicole Brown Simpson. In typical Kim fashion, she took to Snapchat to give her fans a close-up look of the jewelry, which featured a stunning cross pendant.

Kourtney looked equally as fabulous for dinner, sporting a chic camel-colored suede dress with matching wedges and a ruby red pout. Like her sister, she accessorized with a choker, opting for a smaller, gold piece.

During another outing, Kim pulled out all the stops in a body-hugging skirt, which she styled with an off-the shoulder ruffled top and strappy heels. Her hubby kept it cool and casual in a simple gray T-shirt, distressed denim jeans and, of course, a pair of Yeezys.

The Kardashian crew is rumored to be filming scenes in the country for the 13th season of their hit reality show, Keeping Up With the Kardashians. Khloe made the trip, too, but caused quite a stir over social media on Thursday when she posted a snap of herself posing near a wall that read "Fidel," appearing to reference Cuba's former dictator, Fidel Castro.
