Some apartments allow replanning of the hallway, when a roomy closet can be "sunk" in the wall by borrowing the space of the adjoining room. In some houses, you can carve out a place for a separate dressing room or use it as a dressing room.
The main plus of the dressing room in the hallway is convenience. Gathered on the street - everything is at hand. At the same time, it is absolutely wrong to immediately hide wet clothes in unventilated rooms after coming from the street.
Therefore, even if there is a dressing room, provide a place for an open hanger in the hallway. Moreover, the hanger should not be roomy: four hooks are enough for an ordinary family member's outerwear. The more hooks - the more temptations will clutter the hallway. Make a rule: hang on the hooks only the clothes in which you came from the street. Keep the rest behind closed bathroom doors.
