Another day, another KarJenner product launch!

Kendall and Kylie launch their TopShop swimwear line worldwide on Thursday, and who better to model the skimpy bikinis than the sisters themselves! We hate to be mean, but we think ol' Kyls looks better posing in a bathing suit than her catwalker sibling, but she probably doesn't have the time to break into the modeling industry because she has her hands full with her wildly successful lip kits!

Speaking of the cosmetics must-have, the teenage reality star just added another color to the mix, and this time it's jet black! We're not sure how many people can confidently rock the goth hue, but we have a feeling more than a few people will give it a go!
