I saw a little something called "ombre nails" in my Cosmo the other day. At first I thought "ombre" was the color, then I thought it was the technique, and then I thought it meant "sparkle".
Honestly, I still have no idea what it means.
But I still copied it. Basically I applied 2 coats of an opaque/light sky blue, and let it dry. Then I touched on some plain glitter polish (was just clear polish with glitter in it), just on the tips, and then dragged up slightly in the middle. Let that dry, apply a top coat, and you're all ombre'd out!
Whatever that means. :)
