| You Want… | Go For | Pro Tip | We Like | |
| » A soft, natural line | A pencil liner. Easy to control, the blendable formula is forgiving of mistakes. | Make tiny dots between the hairs along the lash lines for subtle definition. | Rimmel Scandaleyes Waterproof Kohl Kajal Eyeliner ($4; mass retailers) |  |
| » A wearable, daytime-appropriate line | Gel liner. It really lasts, but can be diffused by blending. | After dipping the brush into the pot, wipe off excess liner on a tissue before applying. | Maybelline New York Eye Studio Lasting Drama Gel Eyeliner ($10; mass retailers) |  |
| » A strong, defined line | One of the latest marker liners. Their fine, stiff tip can be used for thin and thick lines. | Hold the marker on its side as close as possible to your lashes, then sweep outward. | Smashbox Love Me Paint Pen Eye Liner ($24; smashbox.com) |  |
| » A bold razor-sharp line with a wet-looking finish | Liquid liner. Ideal for dramatic looks, the fine brush creates clean definition. | Starting at the inner corner, draw short strokes in three small sections, not one long line. | Almay Liquid Eyeliner ($7; mass retailers) |  |
| » A heavy, smoky line | A fat, creamy crayon. The tip is wide, so you’ll get a thicker, more intense effect. | Turn the crayon on its side for a delicate line, or smudge the wide part for a night-out look. | Sephora Collection Jumbo Liner 12HR Wear Waterproof ($14; sephora.com) |  |
