What face shape looks good with an undercut bob hairstyle?

The undercut bob hairstyle works best with round and square faces. The hairstyle does not work well with longer or oval faces, as the style is designed to elongate the face.

The undercut bob style combines the individual features of the bob and undercut hairstyles. The undercut style leaves more volume and length on the top of the head and less on the sides, while the bob haircut features chin-length to collarbone-length hair that frames the face. To combine the two, one side of the head is shaved and made to taper up to the top, while the other side is left in a bob cut.
