Olive & June Mani System ($55 and up)

"Once I realized how much money I was spending on manicures, I became determined to try and learn how to do it on my own," Wu says. "I haven't found anything as easy to use as Olive & June, and their colors are great — my favorite is MM, named for the one and only Mandy Moore."

The brand allows you to build your own mani set, starting at $55. You can choose between one polish for starters, six polishes, or the newest lineup of shades released. After you tack on extra accessories to help you pull off a flawless manicure, you'll be ready to give yourself a salon-quality manicure.
