It's actually quite common to live in a space that lacks closet space, specifically in the bedroom. More often than not amazing apartments require getting extremely creative with hiding the majority of your possessions or organizing them in such a way that you don't mind exposing them.
If you asked the average person to expose the contents of their closet most would say no, but maybe that would change after seeing how beautiful, colorful and inspirational it can be. If you lack closet space in your bedroom try hanging an industrial pipe or shelving unit above your bed and display your colorful collection of clothing. You'll have a closet and headboard in one!
If you're really short on space, hang a pole (ideally painted the same color as the wall) relatively close to the wall so there's just enough room for the clothes to be outward facing — this will double as a closet and artwork. The most popular exposed closet option is to simply purchase (or make!) a clothes rack on wheels or a system that can be hung from the sealing.
Exposed closets don't have to look like you're still scraping by in college — they can be beautiful too!
