Kristen Stewart has gorgeous eyes. I must say, whoever does her makeup is amazing!

This one particular look was done by Jillian Dempsey - McDreamy's wife! :)

I'm not sure if you can see it, but there's a beautiful midnight quartz colour on her lids, and I think it looks AMAZING! The eyeshadow used in this look was Avon's True Colour Eyeshadow in Midnight Plum. I checked, and they don't carry this product in Avon Australia. There are a couple of listings on eBay - but they're not quite worth it:
Avon Midnight Plum: AUD 5 + AUD 15 postage
Avon Eyeshadow set of 2: GBP 5 + GBP 4 postage

You can try the Avon in your home country, or you can check out this alternative: Avon's Waterproof Glimmerstick Eyeliner in Midnight Blue: AUD 6.49 + AUD 2.95 postage). This is a creamy glide-on liner, so it works well for thicker lining and can be used as an intense shadow.

Jillian also broke down the rest of this look for us (tee hee):
