I really prefer the rustic look and I love the idea of using old pipes to create levels of hangers, like this one:
as well as bookshelves, etc. You could repurpose a pallet for the base too, add some casters and it would be moveable to wherever you needed it.
They’re pretty easy to reproduce, you just need a few sections of pipe, I suppose you could also use pvc if you wanted something more lightweight or something that you could paint and change the color of. You could even wrap it with various colors of washi or duct tape for designs.
