The tan lines, though! Kourtney Kardashian hit the pool in yet another sizzling one-piece on Thursday, September 15, at The Setai in Miami Beach.

The Keeping Up With the Kardashians star, 37, slipped her petite frame in the House of CB Amalfi Khaki Ladder Cutout One-Piece Swimsuit featuring an open, plunging neckline and side cutouts accented by skinny straps ($105, houseofcb.com). The steamy style not only showcased her toned body (which she also flaunted on the cover of Cosmopolitan's October 2016 issue), but also, thanks to its cheeky cut, her pert derriere. 

The mom of three — Mason, 6, Penelope, 4, and Reign, 21 months, with her former partner Scott Disick — finished the ensemble with a pair of gold aviator sunglasses and gold bangles.

Of course, eagle-eyed swimsuit lovers will note that this isn't the first time we've seen the one-piece on a celeb. Ariel Winter chose the same suit for her appearance at Just Jared's Summer Bash on August 13. However, she paired the cleavage-baring style with denim short shorts and pointed-toe Christian Louboutin pumps.
