Kim Kardashian cuts quite the figure while exercising in daring cut-out swimsuit

Kim Kardashian isn't afraid of making some risky fashion choices, and if her latest Instagram snap has anything to say it's that she's not done taking risks yet. The KKW founder and mom of four - North, 7, Saint, 5, Chicago, 3, and Psalm, 1 - posted a sexy snap that shows off her famous curves (and a bit more!).

On Friday (May 7), the 40-year-old SKIMS founder shared an Instagram photo of herself exercising in a black, plunging back, thong-swimsuit with high-rise sides and extreme cutouts in the front and back.

The KUWTK superstar captioned the snap with a single puzzle piece emoji — an obvious nod to her unconventional workout outfit’s — and finished off her fitness look with a full face of glamorous makeup and cascading, pin-straight platinum blond hair, down her back.

“Ok now you are just playing with my emotions,” sister Khloé Kardashian commented on the post, while pal Jonathan “Foodgod” Cheban asked, “Is this a private gym? LOL.”
