There are so many different ways that you can do your winged liner but the same one might not look best for your eye shape. Here is a chart that shows you how to do an eyeliner perfect for your suited eye shape. It's very important that you know the different because it will look so much better once you find the right way to do your liner.
I have hooded eyes so i usually do a darker liner and a winged liner everyday because i feel naked without it.
If i were to do a liner that is most common which is the almond eye it would not look nice on me at all. Almond eyes are very gorgeous and easy to do makeup on especially since everything looks nice on them.
Hooded (sad) eyes are a little bit difficult because you have to make sure you lift your eye instead of bringing it down.
