Sisters Kim and Khloé Kardashian sport matching SKIMS swimsuits during tropical vacay

Kim and Khloé Kardashian left fans hot under the collar after the former posted a series of sizzling snaps of their day at the beach wearing matching metallic swimwear on the sand which undoubtedly caught the attention of many onlookers from miles away.

The pair donned matching silver SKIMS metallic swimwear - with Kim Kardashian opting for a two-piece metallic bikini while younger sis Good American founder Koko donned a one-piece equivalent - as they lounged by the tropical beach before they retreated to a nearby outdoor shower to hose their sandy bodies.

The Kardashians reality star, 41, took to Instagram to share the photos with her 326 million followers, captioning the post: "House of Kards."

However, it soon became apparent that her younger sister hadn't initially been aware of the post, as she responded five hours later: "I love a good post without approval lol." Check out the post in question below!
