Cat-eye liner is a classic for a reason - bold but wearable, it can go from sweet and retro to rock and roll with the stroke of a brush. We’ve spotted some new twists on the feline flick on the Fall 2012 runways.

Make a minimalist statement on an otherwise bare face with a shock of blue, as seen in this look by Pat McGrath at Anna Sui...

Get the look: Give eyes the royal treatment with CoverGirl Liquiline Blast in Blue Boom ($8.79). Lancôme Liner Design in Dress-Up Teal ($24.50) packs bold pigments into a gel formula that glides on smooth. 

At Versace, Pat McGrath created this look, where the negative space in the outer corners gives the eye a lift like winged liner would - but feels a whole lot more modern.

Get the look: Artists at Jen Kao used Eyeko Skinny Liquid Eyeliner ($15); its thin felt tip makes drawing precise lines easy. For a smokier look, try a gel liner like Laura Geller Inkwell Waterproof Gel Liner ($33 for two). 

While not for the meek, there’s something so inspiring about the angular shape seen at Mary Katrantzou.

At Altuzarra, Tom Pecheux created a similar look with an squared-off shape and two parallel lines extended outward, plus a metallic blue-brown accent at the inner corners.

Get the look: An angled brush dipped in Smashbox Jet Set Waterproof Eye Liner in Midnight Black ($22) can help you finesse a complex shape. Urban Decay 24/7 Waterproof Liquid Eyeliner in Perversion ($19) features an ultra-fine brush and long-lasting formula.

At Lanvin, the supersized cat-eye extended above the crease for an exaggerated twist on the classic shape.

Charlotte Tilbury created a ‘60s-inspired look for L.A.M.B., which featured a blue line along the lashes and another in the crease (it was just visible above the lid when eyes were open).

Get the look: We like the idea of creating an extra-large wing using soft shades, like Stila Smudge Crayon Waterproof Primer + Shadow + Liner ($22) in Antique and Umber - the effect is less intense than black. Or, to go bolder, try intensely pigmented Maybelline Eye Studio Master Drama Cream Pencil ($7.99). Went too heavy-handed? Clean up with Almay Oil-Free Makeup Eraser Sticks ($5.49).

At Erdem, eyeliner was pared down to devilishly minimal effect with tiny triangles at the outer corners.

Get the look: Use MAC Fluidline in Black Track ($15) with the 208 Angled Brow brush ($19.50) to create a calligraphied line on lids. A felt tip, like the one on CoverGirl LineBlast 24 Hour Eyeliner ($7.99), makes drawing precise shapes simple.

At Giorgio Armani, eyes were a study in contrast with white on the upper, inner lids fading outward to black.

This look from Mugler may be a bit intense for everyday, but we like the idea of accenting a classic shape with touches of white.

Get the look: L’Oreal Paris Voluminous Smoldering Eyeliner in Black ($8.95) has the perfect tip for creating a bold line, and it’s blendable, too. Dolce & Gabbana Khol Eye Pencil in True White ($29) is as pure as its name suggests. Illamasqua Precision Ink in Scribe ($27.50) features a long-wearing liquid formula and a super skinny tip.
