Carmelite habit
If the saint is writing while looking away as if in contemplative ecstasy, and is dressed in a brown habit, that’s St. Teresa of Avila. If she’s dressed in the very same habit but carrying a rose, that’s St. Therese of Lisieux. A man wearing the Carmelite habit and receiving the brown scapular from Our Lady is St. Simon Stock. A bearded man in a Carmelite habit praying before a crucifix is St. John of the Cross.
