Your closet is only as accessible as the door leading into it.
If the closet is eight feet wide and the door is only four feet wide, then you have two feet on either side of the door that is visually obstructed and probably difficult to reach as well.
Bear in mind that passage doors were designed for people to pass in and out of rooms, not to maximize access to the interior of closet space. One way to solve the problem caused by excessively deep corners in a closet is to eliminate the walls and door altogether and treat the closet as a cabintet or wardrobe. The cabinet doors are designed to give access to the whole interior of the storage space so that you can see and reach everthing.
The other advantage to eliminating the doors is that there is no obstruction to placement of drawers or other rollout accessories.
if you have a reach-in closet with deep returns at the sides that make the closet difficult to access, consider demolishing the font wall and door to open the front completely. A closet system can then be designed with doors and drawers that allow maximum access and efficient use of the available space.
The other thing to consider is that the cabinet doors can be built to match your existing cabinetry or to add a new look to a room or space in your home.

The cherry closet pictured here was added in a wide hallway in a master bedroom suite between the sleeping area and the bath.The space is used efficiently and the closet has the appearance of a built-in cabinet.
How important is the function of your closet space to you? Are you squeezing into jammed up spaces to reach your clothing in the deep sides of your closet? Your solution may start with demolition.
