they used the dark brown or reddish brown liner..don't worry it will create the same gothic eyes effect..i've tried to find this kind of make up examples because i'm having the problem like some other goths, where the eyes will look weird with the black liner..
so, mom was like "you can't wear black liner coz you're eyes have the natural dark circle shade, so you have to wear sumthing brown and not black!!"
trust me, mom did say sumthing like that.. --_____--''
