Doesnt seem like she has doublelids. A lot of ulzzangs wear circle lens (which are large lens that give the "big eye" effect). I KIND OF STOLE AN EYE&PS it; how i do my makeup.
**Ulzzangs tend to add brown eyeshadow on the outer corner of the eye.**
Highlight the inner lids, top and bottom, next to the nose, with white eye shadow.
Line the water line with white liner.
Line the eyes with black like so (thick to thin); distorting the lower lash line makes it look bigger.
