There's something about the words 'limited edition' and 'Nars' that when put together, completely throw us into a frenzy. So of course, the new Nars summer makeup collection, Adult Swim, has me lusting after lime green (yes, I said it, lime green) eyeshadow. Adult Swim launches in store April 15, and combines the best of all facets of summer makeup -- pastels, neons, metallics -- and somehow makes it all work together.
