Kendall & Kylie's swimwear collection for Topshop is here!

We were thinking that we hadn't heard some news on Kylie or Kendall Jenner for a few minutes or so, and now we know why: they were clearly working their lil asses off on their new fashion endeavour, a swimwear collection: Kendall + Kylie at Topshop.

Picture Kendall at the sewing machine and Kylie, er, 'supervising', while Kim, Khloe and Kourtney, and Kris, model prototypes. That's obviously how it all went down.

Metallic Harness Swimsuit €55

The pair very generously sacrificed their precious time by showcasing the collection themselves, and don't they look in peak physical condition? The end result, we will admit, is pretty fabulous.

Double Layered Mesh Bikini Top and Pant €66

The entire collection is available now: here are our picks.

• Wetsuit Style Bikini €67

• Tape Detailed Swimsuit €55

Animal Print Bikini €59

Mesh Plunge Front Playsuit €46

Palm Print Bikini €59

What do you think? Worth it?
