A 20-pack of space-saving cascading hangers
I brought waaaayyyyy too many clothes to college (fashion merchandising major, sue me) and these were the ONLY way to get all my clothes to fit in the limited closet space provided in a college dorm. It’s certainly not as nice as having all your clothes hung on the rack normally because you lose some visibility and clothes on the bottom can be slightly difficult to access, but if you’re desperate for space they are a true lifesaver. They’re super sturdy and I never had any issues with them breaking in all four years of college.
