The most primary and vital thing for a good make-up is a good eye-liner. And so here are some eyeliner buying tips just for you readers.

Quality is more important than quantity. Select branded eyeliner. Branded liner would last long.
Select eye-liner which suits your persona. Buy different colors of cheap brands and then figure out which color suit you the most.

Same thing is with the type of eye-liner. You may prefer liquid eye-liner but it may not suit you. So try out the cheap brand first.

Daily eye-liner users may opt for the most common colors like black, brown or grey.

For a heavy make-up or say dramatic look always select black eye-liner. If you are fair then you can also apply brown colored liner for a natural look.

If you want your eyes to be highlighted then go for white eyeliner in the inner corners of your eyes.
For cat look go for blue tones of eye-liner.

Always buy a water proof eye-liner for long lasting effect.
