Simon Doonan, the Creative Ambassador at Large of Barneys New York, once told me that "every woman should have a signature flourish -- crazy sunglasses, neon hair, something special." (His is a floral shirt -- he's unrecognizable in anything else.)

Before he even finished his sentence, I started to feel like the most boring, Plain-Jane woman in the world. (How could I go on living without a signature flourish!?) Then, I realized that I do, in fact, have a signature flourish: my cat-eye liner. It's subtle, but it's there.

The key to my look is the eyeliner itself: I'm partial to eyeliner markers. Over the years, I've used everything from pencils to liquids to gels, but I recently realized that markers give you the cleanest line, are the easiest to apply, and are incredibly versatile. You just have to choose the right one, and you can create just about any eyeliner look you want.

Clearly, I'm not alone in my assessment. A bevy of new eyeliner markers have popped up in drugstores and on Sephora shelves alike, and I've tried them all -- seriously. Here's a breakdown of the best new eyeliner markers -- and my favorite liner looks you can create with each one. Of course they can all be used to draw the perfect baby cat eye -- but I suggest you find your own signature flourish.

Best For: Fine-as-a-hair lines

If you're a no-makeup-makeup person, but you want to define your eyes, this fine-tipped marker is for you. Use the liner to fill in the gaps between your lashes for an effect that's barely noticeable but definitely something.

Best For: A baby cat eye

This marker's fine tip makes it easy to control, yet it's buildable -- so if you want to thicken up the line or add a flick at the end, you can. You can also control the color depending on how much pressure you use -- a light hand will create a dark gray effect while firmer application gives you a solid black line.

Best For: Dual-personality looks

On one end, there's a baby-fine marker that's perfect for drawing precise lines around your tear ducts on between your lashes. On the other end, there's a brush-like tip for feathery wings. The formula is inky and extra black, and of course there's the Tom Ford factor that makes this liner impossibly chic.

Best For: A graphic wing

This calligraphy pen-inspired tip is perfect for creating a cool, graphic look. The slant allows you to easily draw squared-off, straight edges and shapes. (Note: While the pen simplifies things, these techniques are not for the makeup novice. You'll need a steady hand and an eye for symmetry to get a look like this right.)
