Interestingly, Kim isn't wearing her wedding ring in them, so it's not clear when they were taken!
She lucked out though because
We know she's one fit momma, but that doesn't mean she wants to show off all the goods!
We're not so used to one of the Kardashian sisters going so low-key while soaking in the sun, but Kourtney definitely still shines in this simple one-piece.
We just hope next time she rocks those curves for everyone's viewing pleasure! LOLz!
Ch-ch-check out more pics of Kourtney at the beach (below)!
