“Sexy” cats, Freddy Kruger, and Lady Gaga are just a few Halloween costumes that require claws. But before you file your nails into sharp little daggers, try this nail polish trick instead. First, paint your nails with a nude nail polish. Once dry, place two pieces of tape diagonally on the tips of your nails to create a pointy template. Fill in with a gray or black polish. Once the dark polish is completely dry, remove the tape. Instant claws!
