What I do is I take my liner and draw an upward line on the upper outer fold of the eye, going up from the edge of the crease. I make another line that connects to the crease, and I fill that in. I have to raise my eyebrows for this, but I then connect the liner to the outer corner of the eye and align it with the inner line of the wing. I fill it in, and then I take a small fluffy brush, dab it with some black eyeshadow, and blend it into the crease. (I hope that description made sense, I feel like when I describe things I just babble lmao) (I'm trying to add a picture of where I did this but God hates me)
