Is it within Catholic teaching or theology, to say that someone MUST wear a Brown Scapular?

Looking for some guidance from Catholic theologians or people well familiar with Catholic theology. Is is okay to say, that someone **"must always wear their brown scapular"** in order to achieve some desired spiritual end? Even if this requirement is not on its own, but as part of a number of other well established practices? For example, "In order to bring the Triumph of Immaculate Heart, one must pray the rosary, consecrate one's life to Mary .... and **always wear their brown scapular** as a sign of this consecration"
