People that have an oblong face have a forehead, cheekbones, and a jawline that are about the same width, and a narrow chin. If this is your type of face, the best eyebrow shape for you is a flat shape. The straight horizontal lines help make your face appear shorter, therefore balancing it. To achieve this look, try to make the bottom of your eyebrow as straight as possible, respecting its original shape, always. If you go for an angled eyebrow, the straight lines going up will make your face look longer than it is, instead of balancing it. Try to avoid this shape.
