lol eyeliner can be a nightmare! Usually it takes me half an hour the first 3 days, and after that I could put it on with my eyes closed. (but watch out if start using it for several months, it'll be as if you'd never put some
)
Some practical advice: I always put the liner with eyes almost closed when I look in the mirror, so that the line is almost straight. (sorry difficult to explain) It's the best way I found to make a natural line, because if you put the liner when your eyes are open, it'll be more difficult to make a line that fit your eyes.
I usually use black or purple liner, depending on the clothes I wear. I have brown eyes, brown thick hair and black thick lashes, so if I wear a black top with a black liner that's really too dark!
I never lid the bottom lid either: too dark, and I start crying whenever I laugh..
With your eyes Clarity, I think a metallic liner can be very beautiful for evening. For example:
(still) Agnès B.
BTW, as it seems some of you ladies are makeup experts, can someone explain me how Alyssa Milano manages to have these perfectly curved lashed in some episods of Charmed???
