The "KUWTK" stars shared a throwback pic from their recent family trip to the Bahamas and spent some extra time recreating a pose from their 2009 spin-off series, "Kourtney & Khloé Take Miami."
It's been 10 years but KoKo, 34, and Kourt, 40, look even better now.
The fit sisters are both clearly comfortable in their own skin, showing off their bikini bodies wearing revealing two pieces.
"They’re Sisters Not Saints," Kourt captioned the shot.
Khloé looks fantastic, showing all that hard work has paid off. The "Revenge Body" star flaunted her curves in a cheetah-print and chunky gold jewels, while Kourtney glowed in a metallic lilac string set.
It's hard to believe it's been a decade since the sisters ran the streets in the Sunshine State, but you wouldn't know it by their recent snap.
And we're not the only ones who think Khloé and Kourtney are killing the IG game with this pic because Hollywood's A-list is filling up their comments.
Bella Hadid wrote "Amazing," Emma Ratajkowski simply used the heart eyes emojis, and good friend La La Anthony commented, "Well damn!"
