A travel case assembly has a travel case having a plurality of walls defining an enclosed storage space, and an organizer positioned inside the storage space. The organizer includes an enclosing netted fabric wall and netted fabric shelves that define at least one storage compartment, and a collapsible support system supporting and defining the netted fabric wall and netted fabric shelves so that (i) the compartments can be expanded when the shelves are separated from each other, and (ii) the shelves can be stacked into a compressed position.
