What's the difference between a bed skirt, a bedspread, a bed cap and a sheet? Which is better?

1, regardless of the size of the bed, the sheets are more mobile and more convenient to use. It is also very convenient to wash, and it will not be washed with a washing machine because it is too thick. The disadvantage is that it is easy to slide. Which belongs to economy and practicality.

The bedspread must be tailored (bought) according to the bed. The bed will be scrapped if it is changed. Bedclothes and bed skirts belong to the dd of bedspreads, and their function is to make bedspreads difficult to slide down and beautiful. The disadvantage is that the washing machine is too thick to wash, so I have to please it myself. It belongs to the luxurious and beautiful hard version, hahahaha.
