Instead of: NARS Night Flight Eyeshadow, $25

Try: NXY Frosted Ocean Eye Shadow, $5

NARS Night Flight is a beautiful, super-pigmented, navy blue/black eyeshadow with just a hint of shimmer. I always feel like I'm channeling my inner goth-princess when I wear it. Because Night Flight smudges so well, I love to use it to create a smoky eye. But if you get the shadow just a tiny bit wet, it doubles as an amazing eye liner! Night Flight has terrific staying power and doesn't flake all over when I apply it. If Night Flight didn't cost so much, I'd probably wear it every day.

Fortunately, NYX makes an identical shade of eyeshadow for just $5! Just like NARS's version, Frosted Ocean is extremely pigmented and easy to blend. It lasts for hours without budging—in fact, I wore it for nine whole hours before it started to show any wear! There’s a tiny bit of fallout when you apply Frosted Ocean, but I find that a good primer helps prevent that.
