Both reality stars wore a brown one-piece while Kim wore a black bikini to show off their arrival in Cabo.
Both Kim and Kylie, 25, sang their hearts out to "Nobody Gets Me" during their Instagram Story clips. The SOS Tour started March 22.
Kendall Jenner, 27, and Kourtney Kardashian, 43, appear to be absent from The Row's spring 2023 collection. She wore black elongated sunglasses to complete the look.
Kourtney spent some time on Thursday promoting her new lemme product, Irish Sea Moss Liquid Drops, which she believes is "one of the most powerful plants and mineral-dense superfoods on the planet that naturally contains 92 of the 102 minerals that the human body requires."
On the Not Skinny but Not Fat podcast episode, many fans noted that Kourtney has been more concerned with her own business rather than spending time with her sisters. Khloe was once seen as her partner in crime.
Kim and Khloe's lives have more similarities at the moment, which has resulted in their closeness. They were through the same things, she said.
