Case in point: This spring we decided try cow-print nails after the design made an appearance on Jenner's Instagram, and we predict her recent sunflower manicure will get similar hype through summer. The yellow-and-white floral print — sported by Hadid in the opposite color variation — is a popular pick at many nail salons given the season. Maybe the supermodels got inspiration from all the brightly-colored floral nail looks on Instagram right now?
