If my death doesn't end up sudden and unplanned (who knows, right?), I believe I would have cared to a certain extent. I wouldn't do anything extravagant like putting on makeup or wearing accessories but I would make sure my hair/body isn't grimy or smelly.
I want to die comfortably, on a bed, wearing loose-fitting clothes like pajamas before drifting off into a sleep-like death. Doing so might calm me down more, and whoever comes to pick up my body would be dealing with a clean death. No blood, no fuss. Just a body lying down on the bed as if it's sleeping. Maybe I could even leave a note for them that says "sorry for the inconvenience but thanks for coming."
Eventually, I'd hope my parents cremate me instead of burying me.
