I recommend Holika Holika Lash Correcting Brown Mascara.

This mascara is perfect for brown eye makeup or when you want to create a soft impression. It is part of the Holika Holika Lash Correcting Series, famous for its green tube and toothbrush-shaped brush, but the brown shade features a regular brush shape instead of a toothbrush. However, true to its description as a "Long Extension," it contains fibers to extend your lashes.
