But here's a trick to make it easier and much more faster: duck tape! Yeah you heard me, duck tape is one of the professional makeup artists best kept secret, and a girls best friend when we're in a hurry.
Cut a little piece of duck tape (the size of your thumb), stick it to your hand and remove it 3 times, in order to remove the excess of glue. Then place it in the upwards direction from the outer corner of your eye, and get the eyeliner. This trick works with either a gel eyeliner, liquid or pen. Draw the wing as you want, and don't worry too much about the shape, as the duck tape is there to make it perfectly defined. when you're done, remove the duck tape and re-touch the area with the foundation or with the BB Cream, in case you're using it.
If you want to achieve this effect but not in a dramatic way, for daytime for example, try Younique Moodstruck Minerals Pigment Powder in the tone Corrupted, mixed with 1 or 2 drops of the Younique Rose Water to create a liquid liner perfect for daytime, office or college.
