The bottom line when it comes to this simple nail art? It looks great in any color combo. (Considering the holiday, manicurist Casey Herman—who also designed the look—opted for a fresh take on traditional red and blue.)
First, start with clear base. Then, dip a striper brush in China Glaze nail polish in "Too Busy Being Awesome" ($7; sallybeauty.com) and create a diagonal line from the bottom right to mid-left side of the nail.
Following the direction of the diagonal line you just created, use China Glaze nail polish in "Applejack Of My Eye" ($7; sallybeauty.com) to paint the upper third of the nail.
Finish with clear top coat, and you've got yourself a Fourth of July mani that won't look stale come July 5th.
