From black bikinis to black leather.

Kim Kardashian shared some memories from her family vacation to Turks and Caicos on Instagram Tuesday, with the “Kardashians” star posting photos from the beach in a black string bikini.

The Skims founder, 43, showed off her fit figure in a cheeky black two-piece in the photos, captioning the sunny snaps, “Cake Boss.”

Kardashian gave fans a look at her booty in the first pic, posing in the turquoise water with her back to the camera.

The Skkn by Kim founder — who wore her hair down in a loose wet look — then stripped off a white tank top while standing in the sea, revealing her toned abs and two gold belly chains.

She lounged in the water in subsequent pics, striking multiple sultry poses on the tranquil beach while sporting a chunky cross necklace.

“OMG the thirsty caption is gold” sister Khloé Kardashian, 39, commented on the post.

“Cake looking good,” a fan wrote, while another added, “Damn ❤️ Kim is back 🌹❤️.”

“Omg Buddy Valastro seems so different” one Instagram user joked, referring to the “Cake Boss” baker.

In other photos posted from earlier on the vacation, Kim sported a sizzling brown snakeskin Skims bikini — and matched with Khloé — as she posed in a Beyoncé-esque Stetson cowboy hat ($750).

Meanwhile, back in Los Angeles, the mom of four covered up in a black leather trench as she joined her 10-year-old daughter, North West, for a Lakers game Tuesday night.

The duo both wore head-to-toe black ‘fits for their outing, with Kim wearing Balenciaga pantashoes underneath her belted coat and the tween sporting an oversized leather jacket with baggy black pants.

North’s coat might just have been borrowed from her dad, Kanye West, as she seems to have a penchant for stealing her father’s style over the years.

While spring break might be over, we have a feeling there will be plenty more swimsuit action from Kim soon enough.
