I recommend the Kiss Me eyeliner in brown.

Kiss Me is a super famous item among eyeliners. I think I've been using it for over 10 years. First of all, the staying power is amazing and it doesn't smudge easily, which I love!! The black shade looked too intense and didn't suit me, but I think the brown eyeliner is perfect for a spring warm tone. I've lost count of how many I've gone through haha. There's quite a lot of product, so once you buy it, it lasts a long time.
