With "ghosts" proper I would think they are imprints in the energy field left after some strong emotion in history.
They are more like watching a video of some past imprint.
So obviously clothes would coincide with the period they are from.
Spirits are more complex.
They can sometimes appear in clothing or robes (for example).
They can appear as we saw them last, as they died, and often very much younger.
I think spirits project into our minds how we see them - or sometimes just feel them.
There may be a message in the clothes, and whatever they or we feel comfortable with.
Most of the Americas, Africa and Oceania were nude just two century ago (Pocahontas did naked cartwheels in front of the Puritans) and they saw ghosts
and believed in the spirit world, so I guess not all ghosts wore clothes, but in a nude culture that was probably not worth mentioning.
Ultimately I think they want a recognizable mark of their identity, and a nude phantom has no markers in our society.
Even ghosts of the living and those just dead (especially in war) will appear in uniform.
So spirits have a system of signs related to our culture - spirit semiotics?
However, I think the spirit is energy, and how we perceive it depends on our mind coupled with their consciousness.
So a feeling the spirit is sending us when we glimpse it is interpreted as meaningful clothes by our mind.
