5. Sleek, Straight, and Center-Parted

While it might seem counterintuitive, a long, poker-straight cut with a sharp center part can be very slimming for a round face. The two long “curtains” of hair framing your face act like a frame for a picture, hiding the width of your cheeks and creating two vertical lines that pull the eye straight down. For this to work, the hair must be long (at least past the shoulders) and kept very smooth. Avoid too much volume at the sides, as that would counteract the slimming effect.
