Kylie Jenner has made a return to her blue hair and completed the mermaid look with a seriously slashed swimsuit in her latest Instagram selfie.

The 17-year-old appeared to be hanging out at home in Calabasas when she took the snap, which shows her wearing a black one-piece with ladder detail to the front and sides, drawing attention to her impressive cleavage.

Here’s hoping Kylie had plenty of Factor 50 on – or those would be some truly awful tan lines!
