Long, side-swept fringe go well with any emo cut and will flatter a round face. Using accent colour in the fringe will camouflage the wideness of the face. A cut with layers in the top and some length around the perimeter can add contouring--style with a holding product for volume.
Looks to Avoid
Short fringe can make a round face appear wider. Avoid parting your hair in the centre, which widens a round face. Consider adding loose curls with a curling iron or hot rollers, since straight, limp hair will maximise fullness in the face.
Most styles can be tweaked to be well-suited to a round face. Look for layers in the crown, long, side-swept fringe, and accent colour in the fringe or around the face. Choose some looks you like and consult your stylist--she'll be experienced in flattering all kinds of face shapes.
