【Bearing】 , 【deportment】 , 【demeanor】 , 【mien】 , port,  【presence】 are comparable when they denote the way in which or the quality by which a person outwardly manifests his personality and breeding.

【Bearing】 is the most general of these words; it may imply reference to a person's mental attitude to others, his conduct in society, or his characteristic posture or way of holding himself.

【Deportment】 applies especially to a person's actions in their relations to the external, often conventional amenities of life; it so strongly suggests the influence of breeding or training that in current use it often means little more than behavior.

【Demeanor】 applies rather to one's attitude as shown in one's behavior in the 【presence】 of others.

【Mien】 implies reference both to 【bearing】 and 【demeanor】 , often as suggestive of mood.

【Port 】 implies reference to physique and, especially through long association with such adjectives as majestic, regal, and proud, to a stately or dignified physique.

【Presence】 is more explicit than 【bearing】 ; it denotes a person's 【bearing】 with reference to its power to impress his personality on others or to attract their attention, interest, or admiration.
