If the thought of sparkle makes you cringe ('90s flashbacks! *shudder*), here's a new way to wear it: a simple line of gems along the bottom lashes. Sure, it's not technically eyeliner, but sure looks gorgeous.
Eyeliner can be a bit daunting for people who don't like to wear much makeup, but there's a simple way to try it out: swap black for gray. Charcoal-colored liner is more forgiving than black or brown, but it still offers added definition. (Oh, and just ignore the black line on this model - unless you're feeling really adventurous.)
