6th Mar: There is an option now on your profile page to use "compact" folders. This works pretty well for phone users and others who like less scrolling.
Rule of Cool, as there is little practical purpose for this. Sometimes this is justified by magic or Applied Phlebotinum, but even when it's not, this trope usually appears in fantastic or futuristic settings. In Far East Asian mythology (China, Japan, Korea) one trait the gods have, which is mostly associated with female gods, is the ability to defy gravity. This is reflected in art, where you'll see the gods have flowing hair and stoles that float in the air. A Holy Halo counts as this, when depicted as a floating circlet. Compare Impossibly Cool Clothes, Detached Sleeves (which can even overlap with this). Not to be confused with clothing that gives the wearer anti-gravity abilities.
