Kourtney Kardashian just wore one of the most mesmerising bikini [1] we've seen in recent memory. The 39-year-old star recently shared another picture from her idyllic Italian getaway [2] in which she's posing with her longtime friend Simon Huck while wearing a black bikini that's not not an optical illusion. Kourtney's bikini in question is held together by plastic straps in keeping with this year's sleek PVC trend [3].

Kourtney previously sported a retro orange bikini [4] while sailing around Capri with her boyfriend, and then an unexpected newspaper-print bikini [5] while taking a dip in the pool. Ahead, shop similar clear-strap and barely-there bikinis to turn the heat up on your swimwear lineup.
