A clothing rack is mostly hollow tubing and wheels, so it is light but bends and scatters parts. Strip it, collapse it, and bag the small hardware, and it packs down to a compact bundle.
Pro tip: Use the rolling rack as a mover on day one to wheel wardrobe boxes to the truck before you break it down.
Watch out: Do not move a fully assembled rolling rack loaded with clothes; it is top-heavy, tips easily, and bends the crossbar.
