First you take a blendingbrush and apply the shade bitter all over you crease. Blend it really well and make sure you blend it a little bit above your crease as well. Then take a regular flat eyeshdowbrush and apply beat all over your lid. You will probably have to apply a couple of layers to get the blue as pigmented as possible. And voila, you're done. This is very simple but oh so beautiful. Perfect for when you're going out at night.
Voila, these were the three looks I created for you. Ofcourse you can apply eyeliner if you want to. I never do because I don't like the way it looks on my eyes. But feel free to wing it. My favorite look is the second one because I love how it makes my blue eyes pop. Tell me what your favorite look is and if you would want me to do more posts like this.
