For the necktie, the length of the tie will be too short on them and only come to about halfway up the chest. This tie should go at least to the belly button, depending on individual body shapes and forms, of course. For the bow ties, if they do not accommodate the width of the child’s neck and it is too tight, then they have outgrown the bow tie. These sizing guidelines are highly dependent on the individual child and if the ties are manual ties or pre-tied items.
