There's something about vampy lips this season, and if you liked Camila Belle's look at the MET Ball, I have a few tips that can help you achieve her lips ;)
You can use L'oreal's Color Riche Lipstick in Intense Plum. I also used Nars' lip liner in Train Bleau, to darken the lips even more. Remember to put the lip liner first, then lipstick. Make sure to blend the liner and the lipstick, to remove any hard edges.
It's a deep burgundy color that will really help you get those dark vampy lips.
For this look, I just used L'oreal's Eyeshadow in Beige Harmony and L'oreal's Super Carbon Liner plus heavy mascara to keep everything simple. A little contouring and highlighting also helped enhance my non-existent cheek bones. Haha.
With Camilla Belle, she just had strong brows, mascara, dark contours, shimmer, highlighting, and really simple eye make up.
REMEMBER: The lips must get ALL the attention.
