Kim, 38, looked sensational as she displayed her toned figure in the electric blue swimwear.
The cut-out detailing exposed her impressive abs, with the mother-of-four accessorising with a pair of blue sunglasses and a simple gold necklace.
Kim's long, black hair appeared to be wet and was curling in the sun, suggesting that the reality star had enjoyed a dip in the pool earlier in the day.
The beauty was also sure to keep hydrated, chugging a bottle of San Pellegrino water as she rose from her sun lounger.
Kim has been joined by her two oldest children, six-year-old North, and three-year-old Saint, who she shares with husband Kanye West.
The celebrity power couple are also mum and dad to 17-month-old Chicago and baby Psalm, who they welcomed in May of this year. (Sat 22)
