I went into MAC with the intention of finding Kinda Sexy, but they were out of stock, so after looking like a diseased creature from swatching my entire left hand I decided on Mehr, which I hadn't heard of before but is in the Matte range. Below is it swatched without any liner which gives it a really nice natural 'no makeup' feel.
I think that the secret behind Kylie's look and the reason she's come under fire for having lip injections is because she structures her lips to make them look fuller by using a darker liner. I'm lucky in that my lips are relatively full anyway so I don't need to overdraw, but using a liner definitely makes a big difference.
Below is Mehr lined with Max Factor liner in #10 Ruby. I do feel this is quite a close match to Kylies lips colour-wise, and am quite glad Kinda Sexy was out of stock because otherwise I wouldn't have found Mehr. Silver linings!
