Kim Kardashian's relaxing getaway in Turks and Caicos was filled to the brim with bikinis. The reality star and multi-hyphenate went on holiday with sister Kourtney Kardashian and the two shared so many sultry snaps on Instagram. In the midst of sporting a red Chanel bikini and blindingly neon pink bikini, Kim switched it up with a sporty black bikini. Well, two black bikinis technically. Kim first shared a picture posing in a vintage top with the Fendi logo printed all over it, but then she later changed into a much simpler, all-black option.
