I think plum eyeliner looks great on brown or hazel eyes. I think you should go for it! You could also try some gold tones on your eyes. Good Luck :)
NYC or Wet n Wild. I know they are the cheapest brands but I really think they work the best!
try maybelline`s shadow stylist loose powder .. it`s kind of an eye shadow, but if you use it as an eyeliner, it will dry in a second and last for the whole day (and night!!!)
