, 38-year-old Khloe shared a bunch of photo updates from her vacation in Turks and Caicos.
In the pictures, she showed off her slim figure in a sexy black bathing suit while relaxing in the clear ocean waters.
The mom-of-one and Good American founder even held a pina colada in her hand as she took a well-deserved break from her life in Los Angeles.
But Khloe made sure that the vacation was a family affair by bringing along her daughter True, four, whom she shares with her ex Tristan Thompson, 31.

Posing in the Chanel swimsuit, Khloe flaunted her tiny waist and toned arms after years of intense workouts and strict dieting.
However, some fans were worried that the Keeping Up With The Kardashians alum has taken her apparent weight loss too far.
“Khloe’s waist looks skinnier than her arm,” wrote one social media user.
Another posted: “Her arm looks so toned but it’s the same size as her waist. I hope Khloe is ok.”
A third agreed: “So skinny, look at that tiny waist.”
WHAT THE NECK?
It’s not the first time that Khloe has worried her followers with her skinnier-than-ever appearance.
Last month, fans described Khloe’s thigh as “thinner than her neck” when she posed in a skintight pink dress for her birthday celebrations.
Khloe enjoyed an over-the-top house party at mom Kris Jenner’s mansion to mark her 38th birthday.
However, some fans were concerned by photos of the Hulu star wearing the pink figure-hugging mini-dress, with one writing that she “looks way too thin now.”
‘CHISELING MY BODY’
Khloe has been working out and following a strict diet ever since her breakup with NBA star Tristan, who infamously cheated on her with Maralee Nichols.
Khloe opened up about her fitness routine in a Hot Ones interview, saying: "I have been working out on more chiseling my body. I like muscles. It is really empowering."
Her personal trainer Joel Bouraima has previously spoken about how dedicated she is to their morning workouts, even arriving at the gym 30 minutes before their regular 6am sessions.
In terms of diet, she sticks to low-carb, high-protein meals with plenty of snacks and water.
Khloe is a self-described “foodie” who has said in the past that she likes to work out so she can eat the foods that she enjoys.
