The Jenner sisters love to keep us guessing.

Back in April, Kylie shared a scintillating preview of her latest project with a behind-the-scenes ‘gram (and accompanying Snapchat videos) of herself wearing a yellow and black cutout bikini. So what, exactly, was she busy doing? It turns out the dynamic duo is officially extending their successful Kendall + Kylie fashion line with a swimwear collection for Topshop, set to drop on June 9.

Kendall offered a preview of the line Tuesday, taking to Instagram to post a shot of herself soaking up the sun in a sporty white and orange bikini (above). Kylie also gave her fans a glimpse of the covetable items and uploaded three images of herself in the same yellow two-piece we saw her in a few months ago. This time, the makeup and beauty professional even delivered a dose of #fitspo, thanks to a few up-close shots of her toned bod.

In February, the siblings released their spring 2016 Kendall + Kylie collection, which includes contemporary separates and accessories perfect for emulating each of their distinct personalities and tastes. We’re sure this next one’s bound to enjoy poolside success.
