All the products I have from there so far have been very neutral nudes, so I was surprised that this colour was a little more fruity than the rest. Sin is a gorgeous rosey berry that will perk up your complexion.
I like to use this as a lip liner first and then fill in the colour. The texture is semi-matte which means it feels comfortable but is long lasting, and definitely no transfer.
If you want a NudeStix eye partner for Sin, try out Smoke. It's a greyish/brown eye pencil that compliments the colour perfectly. These are my current partners in crime!
Colour Intensity: medium
Overall Rating: 3/5 - only because I hate sharpening things (sorry, I'm lazy!)
