Ladies, it's time to ease up on those nail clippers and invest in some extra polish.

From this season's color blocking to fall's metallic shades, nails have been stealing the spotlight. And now, with an emerging trend of extra-long nails, they're taking it more ferociously than ever.

The beauty team at Refinery29.com first caught on to the talon trend backstage at New York Fashion Week Fall 2011, and when celebrities like Katy Perry and Rihanna flashed their claws at this year's Grammy Awards. Since then, manifestations have ranged from the raunchy -- as seen in Tom Ford's Neroli Portofino ad campaign -- to the terrifying.

Where will this long nail trend wind up? One thing is for sure, catfights just got a lot more dangerous.
