This is a very common makeup style. But it's also quite easy to master.
Here's how I do it:
I always start with Mascara. Volumizing, and lengthning.
Add a light coat of black eyeshadow like I've done in the picture. You might have to re-try it a few times to really get the right shape.
When your satisfied with the shape, start adding more black eyeshadow evenly on both eyes.
Add white eyeshadow in the inner conner, and black eyeliner on the top and bottom lash line. You can also add multiple lashes to create a more dramatic eye, or you can just leave it the way it is.
