When we're going on a tropical holiday, you better believe we're packing Instagrammable bikinis. Need some inspiration? Turn your attention to Kourtney and Kim Kardashian [1] who've been giving us major swimsuit envy with their 'grams during their Turks and Caicos getaway [2].

Kim packed a Chanel bikini [3] and a neon pink one [4], while Kourtney showed off her toned abs in a metallic gold two-piece [5] and a crochet bikini [6]. Most recently the sisters, along with their friend/beauty mogul Kristen Ann Crawley posed in a golf cart wearing matching swimsuits.

Kim rocked a black crop top with yellow high-waisted bottoms that featured a black band across the top. On the other hand, Kourtney rocked a black scoop-neck top with a pair of pink bottoms that also had a black band across the top. Read on to get a closer look at their twinning moment [7], then buy similar bikini styles ahead.
