She may have retired the Hannah Montana ensemble, but for Halloween, Miley Cyrus channeled her inner Harajuku Barbie with a Nicki Minaj-inspired costume. We're loving her bright makeup, technicolor wig, and animal print bodysuit, but, of course, no Minaj look is complete without a set of candy-colored nails. Cyrus's manicurist, Jenna Hipp, created a neon leopard look for the star, and you can shop the exact nail decals for just $16 at Hipp's OpenSky online boutique! Bonus: 100 percent of the proceeds from Hipp's shop will go toward the American Red Cross to benefit victims of Hurricane Sandy. An instant mani that looks good and does good? Now that certainly has our heartbeats running away! Pick up a set at opensky.com, and click through our gallery for more celebrities in costume.
