Kim Kardashian shows off her 24-inch waist in a bikini top and belly chain as she joins Chicago and Saint in building sandcastles on the beach in Turks and Caicos.

Kim Kardashian took a break from her businesses like SKIMS and SKKN to spend some quality time with her family on a pristine white sand beach in the Turks and Caicos Islands on Monday.

The Keeping Up With The Kardashians veteran, 43, looked in the best shape of her life as she showed off her 24-inch waist surrounded by a chic belly chain.

Kanye West's ex-wife wore a tiny black triangle top and matching bikini bottoms that showed off her famous behind.

She later donned a white crop top and long basketball shorts, as well as white sneakers, all from Chrome Hearts.

The Vogue cover girl carried a pink bucket as her jet black hair fell over her bare shoulders and she wore barely any makeup.

Also with the Selfish author were two of her children with rapper West: Chicago, six years old, and Saint, eight years old.

Also behind the diva was brother Rob Kardashian's daughter, Dream Kardashian, whose mother is Blac Chyna, but there was no sign of Rob that she prefers to stay out of the spotlight.

And some friends were also present during their walk on the beach.
