Try The Container Store.

Sushipup1: our master closet system comes from Container Store but we need something that uses corners better for our daughter’s closet.

Maybe post a floor plan of the closet if you really want help.

I like the Closet Maid Style +. We used that in our closets because I like the corner system.

We got ours at Home Depot and my hubby assembled it according to our needs.

Not knowing what your setup is now, there isn't much to suggest. What do the corners look like now and what type of additional storage do you need?

Thanks to everyone who commented. It is a very small walk in closet, about 58 inches deep and 58 inches wide. It has a standard size door (about 28 to 30 inches) that opens in to the closet. There is a 16 inch wall/bump by the door that reduces the available hanging wall from 58 inches to about 42 inches on one side. I have been meaning to post the layout (the closet is so small, it’s hard to take photos). Given its awkward size, I need to maximize every inch. Thanks again!
