What is a one-sentence summary of the following article?
Before you apply any makeup, you'll want to determine what will look the most natural on your eyebrows and the shape you want to achieve. To find the right length for your eyebrows, use a pencil and measure a 45-degree angle reaching from the outside of your nose to the outer corner of your eye. Traditionally, your brow should end where the pencil meets your eyebrow. The outside edge should be parallel or slightly higher than the inside edge. The inside of the eyebrow should line up with the center of your nostril.The arch should be positioned above the outer third of your eye. If you have an oval face, you may want to go for arched brows that are a little longer. For a heart-shaped or square face, choose a rounded brow. For a rectangular face, try curved brows. If you have a round face, choose an arched brow.
Decide what your eyebrows should look like.
