Are those white shelves built in? If they have to stay there it’s going to be all but impossible to make the space available better organized and suitable for your stated needs (dress hanging etc).

Without a plan of the space it is really difficult to offer any suggestions.

That's wider than 35 inches I think...Why not make use of the closetmaid planner?

The white shelves can come out for sure! I did measure it and it's about 35 inches wide....how would I make a plan of the space?

Okay...follow the directions on the closetmaid site. Basically, you measure :)

You're measuring the wall space without any of the fittings in place.

Depth would be from the back to the front. and width would be side to side.

Don't include door casing in your measurements.

Don't forget that you can also add shelves (or recycle what you take out) above the door space on the inside. It's a great place for things you don't need to access every day.

What is on the other sides of the closet walls? Bedroom, hallway, bathroom? Sketch a floor plan with measurements of this area.

The importan measutements are

• How much space between sides of door molding and each wall.
• Depth
• Width across the back wall.

You can do a lot with shallow shelves on one side and hanging top to bottom (multiple rods) on the deeper side.
