A pair of notches or slits in a collar can prevent the formation of bulky crests or wrinkling when the collar is arranged in an outer open continental style under a jacket, however there is also a propensity for such a collar to curl up at the notches. The invention herein discloses the use of a fastening means by magnets and/or a combination of magnet/ferrous metals to prevent the slit borders, forming the edge surfaces of each back section of the collar, from curling up from the shirt surface. The fasteners are realized with magnets and/or a combination of magnets/ferrous metals which allow the attachment of the tip to the collar band by simply touching the tip to the collar band. The magnets or ferrous metals may be underneath the tip's and the collar's material respectively.
