Here is my very own version of the smoky blue + purple cat eye from Jason Wu A/W 2013. I used slightly different colors but hope you guys like it either way 
Step 1. Draw a line along your upperline with a purple color. Wing it out and bring it up to the crease to create a graphic cat eye shape.

Step 2. Brush a purple eyeshadow onto the eyelid.
