On 13 Feb., known to some as Galentine's Day — a celebration of love and friendship among women — Kim Kardashian and Kylie Jenner spent some quality time together poolside in near-identical thong bikinis. "you my twin," Jenner captioned a photo of their matching attire as they basked in the light from the sunset. "Always and Forever," Kardashian replied. In the comments section, Kourtney Kardashian also chimed in with a dancing women wearing bunny ears emoji. For years, fans have confused photos of all five Kardashian-Jenner sisters. While we imagine flipping through their childhood photo albums might get tricky, there's no mistaking the fact that Kim and Kylie bear an especially striking resemblance to each other. On Instagram, the sisters played into their similar features in two sets of strappy black triangle bikinis. Kylie opted for a simple silhouette with a high-cut waist and spaghetti straps. Kim mirrored her sister's ensemble in a stringy two-piece set with dangling ties on either side of her waist and down her back. They styled the looks with delicate anklets and statement rings. When it came time to snap a few photos, the pair faced each other on their knees on top of a cushioned chaise. With Kim's hands over her head and Kylie's face turned toward the sky, the duo were perfectly in sync as they executed a dual hair flip. Between the sunlight and coordinated outfits, it's difficult to tell who is who in the photo at first glance. Ahead, see if you can ID Kim and Kylie yourself, and shop similar swimsuit styles.
