This set goes with the top sheet I have ordered for my autistic son as he will like the duvet design. My only sorrow is that, for some reason, duvet sets do not have two sheets included which I have all the time. It is much less hassle to launder a top and bottom sheet each week than one bottom sheet and a duvet cover!! There is a similar problem with single duvet sets; they only have one pillowcase included when I need two.
Economy?
