We all scream for ice cream. It is nearly impossible not to feel in a summery mood while sporting an ice cream cone manicure. “This look works best on nails that are longer and filed down to a more round cone shape,” says Hadley. You won’t get that triangle effect if you have shorter, squared-off nails. Hadley also recommends using the Sally Hansen Salon Effects in “Misbehaved,” $9. These are easy-to-apply nail stickers that will give you the look of a cone without having to draw in the lines yourself.
